Product Data Sheet
HEMPADUR MASTIC 45880 45881
SURFACE PREPARATION:
New steel: When used as an intermediate or finishing coat please refer to the d ata sheet for the preceding GALVOSIL or HEMPADUR primer. When used as a primer please refer to the specification. Zinc silicate painted or spray-metallized surfaces: Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by (high p ressure) fresh water cleaning. Zinc salts (white rust) must be removed by high pressure hosing combined with rubbing with a stiff nylon brush if necessary. It is recommended to recoat spray-metallized surfaces as soon as possible to avoid possible contamination. Concrete: Remove slip agent and o ther possible contaminants by emulsion washing followed by high pressure hosing with fresh water. Remove scum layer and loose matter to a hard, rough and uniform surface, preferably by abrasive blasting, possibly by other mechanical treatment or acid etching. Seal surface with suitable sealer, as per relevant painting specification. Repair and maintenance: Remove oil and g rease, etc. with suitable detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to minimum St 2 (spot-repairs) or by abrasive blasting to min. Sa 2, preferably to Sa 2½. Improved surface preparation will improve the performance of HEMPADUR MASTIC 45880/45881. As an alternative to dry cleaning, water jetting to min. Wa 2½ (ISO 85014:2006)(or according to specification), may be used. A flash-rust degree of m aximum M (ISO 85014:2006) is acceptable before application. Feather edges to sound and intact paint. Dust off residues. On pit-corroded surfaces, excessive amounts of salt residues may call for water jetting, wet abrasive blasting, alternatively dry abrasive blasting, high pressure fresh water hosing, drying, and finally, dry abrasive blasting again.
APPLICATION CONDITIONS:
Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Use only when application and curing can proceed at temperatures above -5°C/23°F (recommended lowest temperature is 0°C/32°F) for HEMPADUR MASTIC 45880 and above approx 15°C/59°F for HEMPADUR MASTIC 45881. The temperature of the paint itself should be 15°C/59°F or above, but advantageously below approximately 30°C/86°F to secure proper application properties. Optimal spraying properties are obtained at a paint temperature of 1822°C/64-72°F. In warmer climates, the paint should be stored in a cool p lace and the paint temperature should preferably be kept below 30°C/86°F. In confined spaces provide adequate ventilation during application and drying. In cases where faster drying at very l ow temperatures is required, HEMPADUR MASTIC 45880 may advantageously be replaced by HEMPADUR 45143. Please also see separate APPLICATION INSTRUCTIONS.
PRECEDING and SUBSEQUENT COAT: None or according to specification. REMARKS: VOC - EU directive 2004/42/EC:
45880 As supplied 5 vol. % thinning Limit phase II, 2010 VOC in g/l 220 250 500 45881 As supplied 5 vol. % thinning Limit phase II, 2010 VOC in g/l 220 250 500 For VOC of other shades, please refer to Safety Data Sheet. Certificates have been issued under the former quality number 4588. Certain lead-free red and yellow colours may discolour when exposed to chlorine- containing atmosphere. Leaded colours may become discoloured when exposed to sulphide-containing atmosphere. Like other epoxy coatings in white/whitish colour a yellowing may take place in cases of application under unfavourable weather conditions, especially sudden drops in temperature during drying and initial cure and/or lack of ventilation. The natural tendency of epoxy coatings to chalk in outdoor exposure and to become more sensitive to mechanical damage and chemical exposure at elevated temperatures is also reflected in this product. May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and recoating interval. Normal range dry is 125-200 micron/5-8 mils. May be specified in lower film thickness for which purpose additional thinning is required, pl ease see separate APPLICATION INSTRUCTIONS. Avoid application of excessive film thicknesses.

Product Data Sheet
HEMPADUR MASTIC 45880 45881
Application onto zinc silicate or spraymetallized surfaces (thinning): Curing agents:
It is recommended to apply HEMPADUR MASTIC 45880/45881 by using a "mist-coat" procedure Provided the paint temperature is approximately above 20°C/68°F: A thin, undiluted coat is applied (the mist coat) and after a few minutes, a second coat is applied in the full specified film thickness. If the paint temperature is below 20°C/68°F, thinning (max 15%) may be required. Curing agents 95880 and 95881 are hazy. This is intended and has no negative influence on the performance.
Note:
HEMPADUR MASTIC 45880/45881 is for professional use only.

HEMPADUR MASTIC 45880/ HEMPADUR MASTIC 45881 High temperatures: 45881: BASE 45889 with CURING AGENT 95881 Low to medium temperatures: 45880: BASE 45889 with CURING AGENT 95880
Scope:
These Application Instructions cover surface preparation, application equipment and application details for HEMPADUR MASTIC 45880/45881.
Surface preparation:
General: In order to obtain best performance, abrasive blast cleaning is recommended. However, HEMPADUR MASTIC 45880/45881 has “surface tolerant” properties and offers higher performance than many other coatings when applied to surfaces mechanically cleaned only (salts, oil, grease etc. shall always be removed).
Remove oil and grease with suitable detergent, salt and other contaminants by (high pressure) fresh water cleaning. NEW STEEL: When used as intermediate and/or finishing coat, surface preparation according to Product Data Sheet for the preceding primer coat (HEMPADUR primers). When used as a selfpriming coat, surface preparation according to specification. When applied to GALVOSILS: HEMPADUR MASTIC 45880/45881 can be applied when the GALVOSIL is cured. Consult APPLICATION INSTRUCTIONS for the relevant GALVOSIL. Remove oil and g rease etc. with suitable detergent. Remove salt and other contaminants by high pressure fresh water cleaning. After exposure to high humidity, zinc salts, "white rust", must be removed carefully by high pressure fresh water cleaning, if necessary combined with scrubbing with stiff nylon brushes. REPAIR AND MAINTENANCE: Spot-repairs: Clean damaged areas thoroughly by power tool cleaning to minimum St 2 (spot-repairs) or by abrasive blasting to minimum Sa 2, preferably Sa 2½. Improved surface preparation will improve the performance of HEMPADUR MASTIC 45880/45881. As an alternative, water jetting to minimum Wa 2½ (ISO 8501-4:2006)(or according to specification) may be used. A flash-rust degree of maximum M (ISO 8501-4:2006) is acceptable before application. Feather edges to sound and intact areas. Brush off loose material. Touch up to full film thickness. Compatibility: HEMPADUR MASTIC 45880/45881 may be used in connection with other generic paint systems than epoxy and polyurethanes. It is recommended to make a test patch. In any case it is a must that the old paint system is tightly adhering and is properly prepared before the touch-up is performed. Full coating: Compatibility with old system: In general full compatibility can be expected with old epoxy systems. A test patch should always be performed before full coating is decided. If the old epoxy is not weathered/chalked or if it is topcoated with polyurethane, it is recommended to roughen the surface before recoating. Furthermore, very thorough cleaning is a must. Any dirt, chalked surface material, oil and grease should be removed with suitable detergent followed by high pressure fresh water hosing of the entire surface. Removal of old system: Full coating after complete mechanical removal of an old paint system is possible too. Yet, it must be considered that mechanical cleaning by disc grinding or by rotating wire brushing may produce a very smooth surface which reduce the adhesive forces of the primer coat

Application Instructions
HEMPADUR MASTIC 45880/45881 Note: Another risk is remains of a hard black rust scale being cleaned to an apparent brightness without showing any adhesive defects. Yet, the exposure to open air during cleaning may have started a further oxidation of the hard black rust making it mechanically weak and of poor adhesion to the underlying steel surface. Later, during service, the scale plus overlaying paint material may flake off. When used for immersion service, repair: Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (minor areas) or by abrasive blasting to min. Sa 2, preferably Sa 2½. Improved surface preparation will improve the performance of HEMPADUR MASTIC 45880/45881. As an alternative to dry cleaning, water jetting to minimum Wa 2½ (ISO 8501-4:2006), may be used. A flash rust degree of M, preferably L (ISO 8501-4:2006) is acceptable before application. Feather edges to sound intact areas. Dust off residues. Touch up to full film thickness Note: On old steel surfaces having been exposed to salty water, excessive amounts of salt residues in pittings may call for high pressure water jetting, wet abrasive blasting, alternatively dry abrasive blasting, high pressure fresh water hosing, drying, and finally, dry abrasive blasting again. Application equipment:
HEMPADUR MASTIC 45880/45881 being a high solids and a relatively high viscosity material, may require special measures to be taken at application. Recommended airless spray equipment:
Pump ratio: Pump output:
min. 45:1 12 litres/minute (theoretical)
Input pressure: Spray hoses:
min. 6 bar/90 psi max. 100 metres/300 feet, ½” internal diameter max. 30 metres/100 feet, 3/8" internal diameter max. 6 metres/20 feet, 1/4" internal diameter
Regular surfaces: Nozzle size:.021" through .023" Fan angle: 60°.
Complicated surfaces (and touch up): Nozzle size: .017" through .021" Fan angle: 40°.
After finishing the application, clean the equipment immediately with THINNER 08450 or HEMPEL’S TOOL CLEANER 99610. Note: Increasing hose diameter may increase paint flow, thereby improving the spray fan. If longer hoses are necessary it may be necessary to rai se the pump ratio to 60:1, maintaining the high output capacity of the pump.
Alternatively up to approx. 5% THINNER 08450 may be added, but thinning must be done with care as the anti-sagging properties are drastically reduced by overthinning. Airless spray data are indicative and subject to adjustment. Induction time:
Should the paint temperature as an exception be 15°C/59°F or below, it is an advantage to allow the two components to prereact before application. This is especially relevant in the case of substrate temperatures also being below 15°C/59°F. In case of a paint or substrate temperature at 15°C/59°F, an induction time of 15 minutes is recommended. In case of a paint or substrate temperature at 10°C/50°F, an induction time of 25 minutes is recommended. In order to obtain proper application properties, the paint temperature should preferably never be below 10°C/50°F. Yet for substrate temperatures below 10°C/50°F an induction time of 30 minutes is recommended.

Application Instructions
HEMPADUR MASTIC 45880/45881 Spray application:
Film-build/continuity: With this paint material applied in one/few coat(s) it is of special importance that a continuous, pinhole-free paint film is obtained at application of each coat. An application technique which will ensure good film formation on all surfaces must be adopted. It is very important to use nozzles of the correct size, not too big, and to have a proper, uniform distance of the spray gun to the surface, 30-50 cm should be aimed at. Furthermore, great care must be taken to cover edges, openings, rear sides of stiffeners etc. Thus, on these areas application of a stripe coat will therefore be good painting practice. To obtain good and steady atomizing, the viscosity of the paint must be suitable and the spray equipment must be sufficient in output pressure and capacity. At high working temperatures, use of extra thinner may be necessary to avoid dust-spray.
The paint layer must be applied homogeneously and as close to the specification as possible. Avoid exaggerated film thickness due to the risk of sagging, cracks and solvent retention. The paint consumption must be controlled. The finished coating must appear as a homogeneous film with a smooth surface and irregularities such as dust, dry spray, abrasives, should be remedied. Brush and roller application:
At application with hand tools, brush, but especially by roller the natural tendency to a more uneven paint film obtained by these methods, is to be counteracted by more coats applied. If at all possible each coat is to be applied across the preceding one - in general follow good painting practise. On poorly prepared surfaces it is always recommended to apply the first coat by brush. Extra thinning will facilitate the penetration of the paint material, but will also require an extra layer to be applied.
Wet/dry film thickness:
Please note that the thixotropic nature of HE MPADUR MASTIC 45880/45881 may give a rather "wavy" surface of the paint just after application. Thi s smoothens at drying, but can make it necessary to let the wet film readings be of a higher value than indicated. In many cases the wet film thickness, reading should be 25-50 micron/1-2 mils higher than calculated. As the wavy surface becomes more smooth during drying these extra wet film thickness readings will not cause a higher paint consumption than otherwise stipulated.
Film thickness/thinning:
HEMPADUR MASTIC 45880/45881 is normally specified in 125-200 micron/5-8 mils. Depending on ambient conditions, usually maximum 5% thinning with THINNER 08450 is relevant, however, increasing at high temperatures to ensure proper film formation and avoid dust spray. May be specified down to 75 micron/3 mils. To obtain optimum film formation in film thicknesses lower than 125 micron/5 mils dry film thickness additional thinning with 5-10% THINNER 08450 is recommended.
Pot life:
When measured under standard conditions the pot life is 1 hour at 20°C/68°F for HEMPADUR MASTIC 45880 respectively 1½ hours at 30°C/86°F for HEMPA DUR MASTIC 45881. However, for a 20 litres/5 US gall ons mix, and used under warm climate conditions, the heat developed by the chemical reaction between BASE and CURING AGENT may make the corresponding practical pot life shorter. Therefore: At high temperatures, use the paint immediately after mi xing irrespective of equipment.

Application Instructions
HEMPADUR MASTIC 45880/45881
Extended recoating intervals can be utili sed when the following is strictly observed:
The surface shall be thoroughly cleaned from all sorts of contaminants including invisible deposits of water soluble salts, oil, grease and similar harmful chemical substances.
Surfaces having any degraded layer from exposure to UV radiation, heat etc. must have this layer removed by mechanical cleaning methods like, water jetting, abrading or sweep blasting.
The existing coating system must in al l respects be sound and applied according to Product Data Sheets, Application Instructions and Specification, It should be recognised that the optimal intercoat adhesion is best ensured by observing the interval between the stated minimum and “Cured Time”. Utilising extended recoating intervals it should further be understood that by chemical nature the intercoat adhesion between HEMPADUR qualities are better than between HEMPADUR and HEMPATHANE qualities. To determine whether the quality of the surface cleaning is adequate, a test patch may be relevant. However, such a test is not the final proof of long-term durability, but if the result is doubtful, repeated cleaning will be relevant. A more safe solution could be to refresh the surface with a new thin (diluted) coat of HEMPADUR MASTIC 45880/45881.
Safety:
Handle with care. Before and during use, observe all safety labels on packaging and paint containers, consult HEMPEL Material Safety Data Sheets and follow all local or national safety regulations. Avoid inhalation, avoid contact with skin and eyes, and do not swallow. Take precautions against possible risks of fire or explosions as well as protection of the environment. Apply only in well ventilated areas.

Product Data Sheet
HEMPATHANE TOPCOAT 55210
APPLICATION AND CURING CONDITIONS:
The surface must be completely clean and dry at the time of application, and its temperature must be above the dew point to avoid condensation. Minimum temperature for curing is -10°C/14°F. At the freezing point and below, be aware of the risk of ice on the surface which will hinder the adhesion. High humidity and/or condensation during application and the following 10 hours (20°C/68°F) may adversely affect the film formation. In confined spaces provide adequate ventilation during application and drying. PRECEDING COAT: HEMPADUR 45141/45143, HEMPADUR MASTIC 45880/45881 or according to specification. SUBSEQUENT COAT: None. REMARKS: VOC - EU directive As supplied 15 vol. % thinning Limit phase I, 2007 Limit phase II, 2010 2004/42/EC: VOC in g/l 445 506 550 500 VOC: For VOC of other shades, please refer to Safety Data Sheet. Certificate has been issued under the former quality number 5521. Colours: Certain lead-free red and yellow colours may discolour when exposed to chlorine- containing atmosphere. Leaded colours may become discoloured when exposed to sulphide-containing atmosphere. To obtain full opacity, an extra coat may be necessary, especially for certain lead-free colours i n eg red, orange, yellow and green. Service At service temperatures above 100°C/212°F, HEMPATHANE TOPCOAT 55210 will become more temperatures: soft. Furthermore, discolouration may occur. Film thicknesses: May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and recoating interval. Normal range is 40-75 micron/1.6-3 mils. Thinning: The type and amount of thinner depend on application conditions, application method, temperature, ventilation, and substrate. THINNER 08080 is recommended in general. THINNER 08510 may be used alternatively depending on local conditions. Airless spray: 5-15% thinning is recommended. Under extreme conditions up to more than 20% may be necessary to obtain satisfactory film formation. The best result is obtained by applying a mist coat of HEMPATHANE TOPCOAT 55210 at first, and then 2-15 minutes later apply to full film thickness giving a uniform film formation. Do not exaggerate the film thickness. Electrostatic spray: 10% thinning with specified thinner is recommended. Please contact HEMPEL for further advice. Recoating and drying/curing time:

Notes:
ISSUED BY:
A completely clean surface is mandatory to ensure intercoat adhesion, especially at long recoating intervals. Any dirt, oil, and grease has to b e removed, e.g. with suitable detergent. Salts to be removed by fresh water hosing. To check an adequate quality of the s urface cleaning a test patch is recommended before a ctual recoating. CURING AGENT 95370 is sensitive to moisture. Store in a dry place and keep the can tightly closed until use. Open curing age nt cans with caution as overpressure might exist.

Product Data Sheet
HEMPADUR 85671 SURFACE PREPARATION:
New steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting to near white metal Sa 2½ (ISO 8501-1:2007) with a surface profile corresponding to Rugotest No. 3, BN10a, Keane-Tator Comparator 3.0 G/S, or ISO Comparator Medium (G). Other degrees of cleaning including wet methods lik e ultrahigh-pressure-water-jetting (UHPWJ) and blas ting with mixtures of grit and water may be relevant according to Hempel-specification. Apply immediately after cleaning. Repair and maintenance: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Old steel surfaces having been exposed to salt water, excessive amounts of salt residues in pi ttings may call for abrasive blasting, high pressure fresh water hosing, drying, and finally, dry abrasive blasting again. Concrete: Remove slip agent and other possible contaminants by emulsion washing followed by high pressure hosing with fresh water. Remove scum layer and loose matter to a hard, rough and uniform surface, preferably by abrasive blasting, possibly by other mechanical treatment or acid etching. Seal surface with suitable sealer, as per relevant painting specific ation.
APPLICATION CONDITIONS:
Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Use only where application and curing can proceed at temperatures above: 10°C/50°F. The temperature of paint itself s hould be 15°C/59°F or above. In-can temperature of the paint s hould preferably be below 25°C/77°F. Curing requires a relative humidity of: max 80%, preferably 40-60%. In confined spaces provide adequate ventilation during application and drying. Reference is made to separate APPLICATION INSTRUCTIONS.

Note: ISSUED BY:
The thoroughly mixed BASE and CURING AGENT must be prereacted before application (15 minutes at 20°C/68°F), at other t emperatures, please see APPLICATION INSTRUCTIONS. May be used under insulation, pipes and the like in one or two-coat systems. Dry film thicknesses should not exceed: 300 micron/12 mils. May be specified in another film thic kness than indicated depending on purpose and area of use Film formation of each coat has to be of good quality, free from defects such as pinholes and without any dry spray. Exudation of the curing agent causes t he mentioned patchy, whitish, and/or greasy formation, which will take place if the product is applied at low temperatures without proper induction time and/or if the coating is exposed to water (rain, condensation) during drying and curing. The minimum total dry film thickness for the system is normally: 300 micron/12 mils The coating should be cured for at least 7 days at 20°C/68°F before exposure to high temperatures. At temperatures above 160°C/320°F, max 205°C/401°F, it is recommended to apply maximum: 2 x 100 micron/4 mils. The coating will discolour at high service temperatures. Keep thinning at absolute minimum. Do not dilute the components separately - only the mixture. The coating is to be applied in a dry film thickness as near as possible to the specified: 100 micron/4 mils Drying and curing conditions have to be according to APPLICATION CONDITIONS until full c uring has been obtained. The surface MUST be completely clean before overcoating. All dust, abrasives and loose dry spray must be removed by vacuum cleaning. Dry spray should be removed by light abrading.The coating may only be exposed to strong direct sunlight or ultraviolet light under exceptional circumstances and then only for short periods. The coating is to be checked carefully and should have no patchy, whitish, and/or greasy formation, which can hinder adhesion of the subsequent coat. Minimum: Non-potable water service: 36 hours (20°C/68°F) between the first and s econd coat, 24 hours (20°C/68°F) between the second and third coat. Potable water service: 3 days (20°C/68°F) between coats. The approval from Folkehelseinstituttet, Norway will apply provided a minimum recoat interval of 6 days (20°C/68°F). Maximum: 21 days (20°C/68°F). If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion. HEMPADUR 85671 For professional use only.
