APPLICATION DETAILS
Application conditions All surfaces must be dry. The temperature of the ambient air or surface should not fall below -15 ºC during application and drying. Relative humidity should be 50 - 90 %. The surface temperature of the steel should remain at least 3 ºC 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 - 3. (ISO 8501-1)
Finishing Temachlor 40, Temacryl AR, Temacryl EA, Temal, Temacoat GPL-S Primer, Temacoat GPL-S MIO, Temacoat RM 40 and Temacoat SPA.

Temasil 90 may be overcoated with above mentioned paints when Thinner 1029 does not dissolve the coat. Before overcoating it is recommended to spray a misty coat with 25 % thinned Temacoat GS 50.
Painting By airless or conventional spray or brush. Agitate during application. Depending on the application method the paint can be thinned 0 - 5 % by volume. Airless spray nozzle tip 0.018" - 0.021" and nozzle pressure 120 - 180 bar. Spray angle shall be chosen according to the shape of the object.

When coating interiors of chemical tanks or working in dry conditions, it is recommended to rinse the paint film with fresh water 1 - 24 hours after application. Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by a brush before the spray application.

Note! There is a risk of mudcracking or peeling with heavier coats than approx. 100 µm dry film thickness.

Separate application instructions available.
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 1029.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 470 g/litre of paint.
VOC content of the paint mixture (thinned 5 % by volume) is 480 g/l.
