High-reactivity aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) trimer chemistry.
Excellent weather resistance and UV stability — ideal for outdoor applications requiring long-term gloss and color retention.
Low viscosity enables easy handling, efficient mixing with polyols, and compatibility with solvent-based and high-solids coating systems.
Provides outstanding mechanical properties including hardness, flexibility, and chemical resistance in cured films.
Compliant with major global regulatory frameworks for industrial coatings, including REACH and VOC-compliant formulations.
Automotive OEM and refinish clearcoats and basecoats.
Industrial maintenance coatings for machinery, agricultural equipment, and construction vehicles.
High-performance plastic coatings for automotive interior and exterior trim parts.
Premium wood coatings for furniture, flooring, and architectural millwork.
Aerospace interior coatings requiring low emission and durability.
