|Painting||By airless spray or brush. Agitate during application. Depending on the application method the paint can be thinned 0 - 10 % by volume. Airless spray nozzle tip 0.015" - 0.021" and nozzle pressure 120 - 180 bar. Spray angle shall be chosen according to the shape of the object. Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by brush before the spray application. At brush application the paint should be thinned according to the circumstancies.|
|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.|
