Low-viscosity aliphatic polyisocyanate trimer offering excellent storage stability and handling safety.
Non-yellowing performance ideal for high-gloss, weather-resistant topcoats in demanding outdoor applications.
High functionality and reactivity with hydroxyl-containing resins (e.g., polyesters, acrylics, polyethers) enabling fast ambient or forced-dry curing.
Compliant with major global VOC regulations including EU Directive 2004/42/EC and US EPA standards for architectural and industrial coatings.
Consistent batch-to-batch quality supported by Covestro’s stringent GMP-aligned manufacturing controls.
Automotive clearcoats and basecoats requiring exceptional gloss retention and UV resistance.
Industrial maintenance coatings for machinery, rail vehicles, and agricultural equipment.
High-performance wood finishes for premium furniture and interior architectural elements.
Aerospace interior coatings where low volatility, non-yellowing properties, and adhesion to composites are critical.
