Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.
Surface Preparation
Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)
Steel surfaces:
Blast clean to grade Sa2½. (ISO 8501-1)
In order to get the best performance the surface profile should be medium grit. (ISO 8503-2)
All surfaces must be clean, dry and free from contamination.
The temperature of the ambient air, surface and paint should not fall below 5ºC during application and drying.
Relative humidity of the air should not exceed 80% during application and drying.
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.
Note! There is a natural tendency of this coating to chalk, discolour or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical requirements on colour appearance.
Mixing 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.
Application
For airless spraying:
The product is thinned depending on the temperature of the components and shape of the object approximately 0–5%.
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:
Product should be thinned according to the circumstances.
Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by brush before the spray application.
