Applications
- Automotive coatings: improves film fullness, gloss and hardness.
- Industrial and wood coatings: suitable for systems requiring high hardness and wear resistance.
- Protective coatings: used for steel structures, oil pipelines and other light- to heavy-duty anti-corrosion applications.
- Styrene foam landscape coatings.
- Wind turbine blade coatings, including gel coat, putty and topcoat.
- High-consistency color paste grinding, especially for automotive refinish coatings, supported by high solids, low viscosity, good wettability and excellent compatibility.
Packing & Storage Information
Packing
200 Kgs/Drum, 10 Kgs/Drum
Shelf Life
FEISPARTIC F523 must be stored in airtight containers to prevent contact with moisture. Recommended storage temperature is below 40°C (≤104°F). The shelf life of FEISPARTIC F523 in the closed original container is 12 months.
Notice
