APPLICATION DETAILS
Application conditions All surfaces must be dry. The temperature of the ambient air, surface or paint should not fall below +5ºC during application or drying. Relative humidity should not exceed 80%. The surface temperature of the steel should remain at least 3ºC above the dew point.
Preparation Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

Steel surfaces: Blast clean to grade Sa2½. (ISO 8501-1) If blast cleaning is not possible, phosphating is recommended for cold rolled steel to improve adhesion.

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)
Priming Temadur 20, Temacoat GPL-S Primer, Temacoat GPL-S MIO, Temabond, Temacoat Primer and Temanyl PVB.
Finishing Temadur and Temathane.
Painting By airless or conventional spray.
Airless spray: depending on the temperature of the components and shape of the object the paint can be thinned 0–15%. Airless spray nozzle tip 0.011"–0.015" and nozzle pressure 160–200 bar. Spray angle shall be chosen according to the shape of the object. In order to reach thicker coats (over 100µm DFT) use always "wet-in-wet" technique.
At conventional spray the paint should be thinned 10–15% to a viscosity of
20–25 s/DIN4.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use Temaspeed Squirrel Mixer for mixing.
Cleaning of tools Thinner 1067 or Thinner 1048.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 380 g/litre of paint.
VOC content in paint (thinned 15% by volume) is 450 g/l.
