Basic Features
For use as a Topcoat on marine applications or in slightly to moderately corrosive environments.
Easy to apply;
Good corrosion protection;
Moderate gloss and color retention.
Recommended Uses
As a Topcoat for conventional alkyd systems on steel and wood, it provides good weathering resistance, color retention, and hiding power.
Surface Preparation
All surfaces should be clean, dry, and free from contamination. Surfaces should be evaluated and prepared in accordance with ISO 8504.
Painted Surfaces: Clean, dry, and in good condition with a compatible primer.
Application Conditions
The substrate temperature should be at least 3°C above the air dew point. Temperature and relative humidity should be measured near the substrate. Good ventilation is usually required in confined areas to ensure proper drying.
Product Compatibility
Primer: Red lead alkyd primer
Sub-Paint: Alkyd intermediate
Topcoat: Alkyd Topcoat
Storage
Must be stored in accordance with national regulations. The recommended storage temperature is 15-25°C. Store in a dry, cool, well-ventilated environment away from heat and ignition sources. Keep the container tightly closed. Shelf life: at least 12 months at 25°C.
Packaging
20 kg/drum.
