Temacoat Primer - Epoxy paint
|DESCRIPTION||A two-component resin-modified epoxy paint containing anti-corrosive pigments.|
Good adhesion to steel, zinc and aluminium surfaces. Used as a primer or an intermediate coat on surfaces exposed to climatic, mechanical and chemical stress. Pigmented with zinc phosphate.
|Recommended uses||Recommended for building frameworks, tubular bridges, conveyors and other steelwork and equipment.|
|Colour Range||Reddish brown (TVT 4000) and grey (TVT 4001).|
Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.
|Mixing ratio||Base 4 parts by volume 008 7252, 7253
Hardener 1 part by volume 008 5611
Base 5 parts by volume 008 7252, 7253
Hardener 1 part by volume 008 5613
|Application method||By airless spray or by brush.|
|Pot-life (+23°C)||6 hours with Hardener 008 5611
4 hours with Hardener 008 5613
Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.
|Solids volume||72 ± 2 % (ISO 3233). Weight solids 83 ± 2 %.|
|Density||1.5 kg / l (mixed)|
|Product code||Base 008 7252, 7253, hardener 008 5611 and hardener 008 5613|
|Application conditions||With hardener 008 5611:
All surfaces must be clean and dry and free from contamination. During application and drying the temperature of the surface should not fall below 0°C. Relative humidity of the air should not exceed 80% during application and drying. The surface temperature of the steel should remain at least 3°C above the dew point.
The product should not be applied at temperatures below 0°C where there is a possibility of ice formation on the substrate. For proper application the temperature of the paint itself should be above +15°C during mixing and application. Good ventilation and sufficient air movement is required in confined areas during application and drying.
With hardener 008 5613:
All surfaces must be clean and dry and free from contamination. During application and drying the temperature of the surface should not fall below -10°C. The surface temperature of steel should remain at least 3°C above the dew point. Care has to be taken that there is no ice on the substrate. For proper application the temperature of the paint itself should be above +15°C during mixing and application.
Good ventilation and sufficient air movement 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||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.
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. For hot dip galvanized surfaces see separate application instructions or contact Tikkurila ProService.
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.
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||Temacoat Primer, Temazinc 77 and Temazinc 99.|
|Finishing||Temacoat GPL, Temacoat GS 50, Temacoat GPL-S MIO, Temacoat 50, Temadur and Temathane.|
|Painting||For airless spraying, the product is thinned approximately 0–10%. Recommended nozzle tip is 0.015"–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 circumstances.
|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.|
|Cleaning of tools||Thinner 006 1031.|
|EU VOC 2004/42/EC-limit value||The Volatile Organic Compounds amount is 280 g/litre of paint mixture.
VOC content of the paint mixture (thinned 10% by volume) is 325 g/l.
