APPLICATION DETAILS
Application conditions All surfaces must be clean and dry and free from contamination. The temperature of the substrate should be minimum 0°C and at least 3°C above the dew point of the air. The product should not be applied at temperatures below 0°C where there is a possibility of ice formation on the substrate. The temperature of paint itself should be above + 15 °C for proper application.
Good ventilation is required in confined areas during application and drying.

Note! There is a natural tendency of epoxy coatings to chalk and discolor on exterior exposure
Preparation Primed surfaces: Oil, grease, salt and dirt are removed from the surface by appropriate means. Repair any damage to the primer coat. Note the overcoating time of primer. (ISO 12944-4)

Zinc surfaces: Sweep blast clean with mineral abrasives, e.g. quartz sand, to an even roughness. (SaS, SFS 5873) If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with PANSSARIPESU detergent.

Hot dip galvanized surfaces are recommended to be painted with a mist coat (paint thinned 20 - 25 %) before the actual priming.

Aluminium surfaces: Sweep blast clean with non-metallic abrasives to an even roughness. (SaS, SFS 5873) If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with MAALIPESU detergent.
Priming Temacoat GPL-S Primer, Temacoat HB Primer, Temacoat PM Primer, Temacoat GPL-S MIO, Temacoat SPA, Temabond and Fontecoat EP Primer.
Finishing Temacoat GPL, Temacoat GS 50, Temadur and Temathane.
Painting By airless or conventional spray or by brush. At airless spray application the paint should be thinned 5 - 25 % by volume. Airless spray nozzle tip 0.011" - 0.017" and nozzle pressure 120 - 160 bar.Spray angle shall be chosen according to the shape of the object. At conventional spray the paint should be thinned about 25 % to a viscosity of 20 - 30 s DIN4. At brush application the paint should be thinned according to the circumstancies.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use mechanical mixer for mixing.
Cleaning of tools Thinner 1031.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 370 g/litre of paint mixture.
VOC content of the paint mixture (thinned 25 % by volume) is 498 g/l.
Only for industrial and professional use.
