PRODUCT DATA SHEET
Temadur SC-F 20 - Polyurethane paint
|DESCRIPTION||A two-component fast-drying semi-matt polyurethane paint, containing anti-corrosive pigments, hardener aliphatic isocyanate.|
Recommended especially to
be used as a single coat finish for agricultural and earth moving machinery and
other machinery and equipment.
|Recommended uses||Storage tank exteriors, steel framework and other steel structures.|
|Features||Excellent weathering and abrasion resistance. Easy to clean and non-chalking topcoat with good gloss and colour retention.|
|Colour Cards||RAL, NCS, SSG, BS, MONICOLOR NOVA and SYMPHONY colour cards. TEMASPEED tinting.|
Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.
|Thinner||1048 and 1067|
|Mixing ratio||Base 4 parts by volume 642 serie
Hardener 1 part by volume 008 7640
By airless or conventional spray.
|Pot-life (+23°C)||app. 1 hour|
Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation. When forced drying in temperatures +50–+100ºC, use flash-off time between 5–30 minutes, depending on the wet film thickness and the actual temperature.
|Solids volume||63 ± 2 % volume (ISO 3233)
77 ± 2 % weight
|Density||1.4 ± 0.1 kg / l (mixed)|
|Product code||642 series|
|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
|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.
