Basic Characteristics
Excellent resistance to various oils;
Easy to apply by spray, roller, or brush;
Excellent salt spray resistance;
Excellent abrasion and impact resistance.
Recommended Uses
Used as a Topcoat for epoxy paints. It can also be used on concrete surfaces or indoors, away from direct sunlight.
Surface Preparation
All surfaces must be clean, dry, and free of dirt. Surfaces must be evaluated and prepared in accordance with ISO 8504. For painted surfaces, a compatible primer must be clean, dry, and intact.
Application Conditions
Substrate temperature must not fall below 0°C and must be at least 3°C above the air dew point. Temperature and relative humidity should be measured near the substrate. Good ventilation is generally required in confined areas to ensure proper drying. When applying the Topcoat, the paint surface should be dry and free of contamination.
Recommended Coatings
Primer: Zinc-rich primer or thick-build epoxy resin paint
Intermediate: Epoxy iron oxide paint
Topcoat: Epoxy Topcoat
Storage
Must be stored in accordance with national regulations. The recommended storage temperature is 15-25°C. The storage environment should be dry and well-ventilated. The packaging container must be kept tightly closed.
Shelf Life: 12 months at room temperature.
Packaging
Component A: 21 kg (base), Component B (curing agent): 4 kg (hardener).
