Applications
- Automotive coatings: Helps improve film fullness, gloss and hardness.
- Industrial and wood coatings: Suitable for high-hardness and high wear-resistance applications.
- Anti-corrosion coatings: Used in protective coatings for steel structures, oil pipelines and other light- to heavy-duty anti-corrosion applications.
- Styrene foam landscape coatings: Suitable for landscape coating applications.
- Wind blade coatings: Can be used in gel coat, putty and topcoat systems.
- Color paste grinding: High solid content, low viscosity, good wettability and compatibility make it suitable for grinding high-consistency color paste, especially for automotive repair coatings.
Packing & Storage Information
Packing
200 Kgs/Drum, 10 Kgs/Drum
Shelf Life
FEISPARTIC F520 must be stored in airtight containers to prevent contact with moisture. Recommended storage temperature is below 40°C (≤104°F). The shelf life in the closed original container is 12 months.
