Aliphatic hexamethylene diisocyanate (HDI)-based trimer with low volatility and excellent weather resistance.
Non-yellowing formulation ideal for high-gloss, UV-stable topcoats and clear finishes.
Controlled reactivity enables extended pot life and smooth film formation in ambient- or forced-dry conditions.
Low monomer content (<0.5%) meets stringent industrial safety and VOC compliance requirements.
Compatible with a broad range of hydroxyl-functional resins including acrylics, polyesters, and alkyds.
Automotive OEM and refinish clearcoats requiring exceptional clarity and long-term gloss retention.
Industrial maintenance coatings for metal substrates exposed to outdoor environments.
High-performance wood coatings used in premium furniture and architectural millwork.
Aerospace interior coatings where non-yellowing performance and low outgassing are critical.
