Low-viscosity aliphatic polyisocyanate trimer based on hexamethylene diisocyanate (HDI), enabling easy handling and solvent-free or low-solvent formulations.
Excellent weather resistance and UV stability, delivering long-term gloss retention and minimal yellowing in outdoor applications.
Fast-reacting with hydroxyl-functional resins (e.g., polyesters, acrylics, polyethers), supporting efficient ambient- or heat-cure coating processes.
Non-yellowing character suitable for high-performance clearcoats and topcoats requiring optical clarity and color fidelity.
Compliant with major global regulatory frameworks including REACH and VOC-restricted formulations for industrial coatings.
Automotive OEM and refinish clearcoats and basecoat/clearcoat systems.
High-end industrial maintenance coatings for machinery, rail, and agricultural equipment.
Premium wood finishes for furniture, flooring, and architectural millwork.
Plastic coatings for automotive interior trim and consumer electronics housings.
UV-resistant coil coatings for architectural metal panels and roofing substrates.
