Application conditions All surfaces must be clean, dry and free from contamination. The temperature of the ambient air and surface should not fall below -15ºC during application and drying. Relative humidity of the air should be between 50–90%. The surface temperature of steel should remain at least 3°C above the dew point. Good ventilation and sufficient air movement is required in confined areas during application and drying.
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) The surface profile must be minimum medium (G). (ISO 8503-2)
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 For airless spraying, the product is thinned approximately 0–5%. Recommended nozzle tip is 0.018"–0.021" and pressure 120–180 bar. Spray angle shall be chosen according to the shape of the object.

For brush application the product should be thinned according to the circumstancies.

Agitate during application. Separate application instructions available.

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. 100µm dry film thickness.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use power mixer for mixing. Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface and weaken the properties of the coating
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.
