ABACOAT PUR-40

SURFACE PREPARATION

Previously painted surfaces: The surface must be completely clean and free of grease or other contaminants. It should be fully dry before painting, and if a long time has passed since the application of the previous coat, the surface should be lightly sanded to create the necessary roughness. Prior to application all surfaces should be assessed and treated in accordance with ISO 8504. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Steel surfaces: The surface should be washed with an appropriate solvent to remove grease, salts, and other contaminants. Rust removal and profile creation should be carried out using methods like sandblasting or mechanical tools. Welded joints and corners should be smooth and free of burrs. After rust removal and profiling, clean the surface thoroughly with dry, oil-free compressed air or vacuum. The primer layer should be applied within two hours of surface preparation.

Aluminum surfaces: Sandblasting or at least sweep blasting should be done, followed by removal of contaminants. Apply thin coats (around 40 microns) initially and build up to the desired thickness with additional layers.

Concrete surfaces: For new concrete, a minimum of 28 days should pass after placement before coating. For older concrete, the surface should be washed with fresh water to remove contaminants like salt deposits, grease, dust, and loose particles. Alkaline degreasers may be used to remove all contaminants, followed by water washing. Surface roughness can be created mechanically using power tools or chemically with appropriate acids (acid pickling). After washing with fresh water and drying, the surface will be ready for coating.

MIXING

After surface preparation and selecting the painting method, stir component A thoroughly, ensuring no sediment remains. Then, add component B in the recommended ratio and mix thoroughly using an electric mixer at 300-400 rpm until the mixture is uniform.

Note 1: Always mix only the amount of paint that will be used within 3 hours.
Note 2: The correct ratio of the two components must be strictly followed; do not alter the ratios.

APPLICATION

Apply the coating via airless spray, brush or roller. Application temperature should be 5 - 40 °C.

Notes:

1. The curing reaction between the polyol and the isocyanate hardener progresses over time, leading to a loss of efficiency. Therefore, only mix the amount of material that can be applied immediately after mixing.
2. In warm climates, the temperature of the components before mixing should be around 25°C to avoid reducing the pot life.
3. The ambient temperature during application should be between 5°C and 40°C.
4. The surface temperature during application should not be less than 5°C or more than 45°C.
5. The relative humidity should be below 80%.
