High-reactivity aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) trimer chemistry.
Low-viscosity liquid formulation enabling easy handling, precise metering, and excellent compatibility with common polyols.
Excellent weather resistance and UV stability — ideal for high-performance exterior coatings.
Non-yellowing character ensures long-term gloss retention and color fidelity in clearcoats and pigmented systems.
Complies with stringent VOC regulations including EU Directive 2004/42/EC (Category C1-b) and EPA Method 24.
Automotive OEM and refinish clearcoats requiring high gloss, mar resistance, and durability.
Industrial maintenance coatings for metal and plastic substrates exposed to harsh environmental conditions.
High-end wood finishes demanding rapid cure, hardness development, and optical clarity.
Aerospace interior coatings where low VOC, non-yellowing performance and adhesion are critical.
