Basic Features
Maintains vibrant color and gloss for a long time.
Excellent weathering performance;
Resists yellowing and chalking;
Excellent salt spray resistance;
Excellent flexibility and abrasion resistance;
Excellent wear and impact resistance.
Recommended Applications
As an ultra-durable, high-quality Topcoat, it is suitable for high-performance steel structures such as offshore wind turbines, offshore oil platforms, bridges, and other steel structures requiring high corrosion protection.
Surface Preparation
All surfaces must be clean, dry, and free of dirt. Surfaces must be assessed and prepared in accordance with ISO 8504.
For painted surfaces, a clean, dry, and intact compatible primer is recommended.
Application Conditions
The substrate temperature must not fall below 5°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.
Product Compatibility
Primer: Zinc-rich primer or thick-build epoxy resin paint
Intermediate: Epoxy micaceous iron intermediate
Topcoat: Acrylic polysiloxane Topcoat
Storage
Must be stored in accordance with national regulations. The recommended storage temperature is 15-25°C. The storage environment should be dry, cool, well-ventilated, and away from heat and ignition sources. The container must be kept tightly closed. At 25°C, the product has a shelf life of at least 12 months.
