Low-viscosity aliphatic polyisocyanate trimer based on hexamethylene diisocyanate (HDI), enabling easy handling and formulation without reactive diluents.
Excellent weathering resistance and UV stability, ensuring long-term gloss retention and color stability in outdoor applications.
Fast curing kinetics at ambient or elevated temperatures, supporting high-efficiency industrial coating processes.
Low monomer HDI content (<0.5%), meeting stringent occupational health and safety requirements for workplace exposure.
Compatible with a broad range of hydroxyl-functional resins including acrylics, polyesters, and polyethers for versatile two-component polyurethane systems.
Aerospace coatings requiring high durability, chemical resistance, and compliance with aviation material standards.
Automotive OEM and refinish topcoats where exceptional clarity, hardness, and scratch resistance are critical.
Industrial maintenance coatings for machinery, steel structures, and offshore equipment exposed to harsh environments.
High-performance wood finishes for premium furniture and architectural millwork demanding low VOC and excellent film formation.
Plastic coatings for automotive interior trim and consumer electronics housings requiring flexibility and adhesion.
