Polyurethane Anti-static Super Wear Resistant Topcoat
Applications:
Composites have almost all the advantages over organic polymers and organic concrete, and are particularly suitable for use in extreme industrial environments such as food hygiene, chemical corrosion, high temperatures and humidity , wet and slippery water, freezing temperatures, and heavy-duty stamping.
Coating properties:
- Strong impact resistance, high wearresistance, service life up to 20~30 years
- Resistant to -40~130℃high and low temperature
- Excellent water vapor penetration
- Very low VOC emissions
- Fast curing property
