Highly reactive aliphatic isocyanate based on hexamethylene diisocyanate (HDI) trimer chemistry.
Excellent weather resistance and UV stability—ideal for outdoor applications requiring long-term color and gloss retention.
Low viscosity enables easy handling, efficient mixing with hydroxyl-functional resins, and improved formulation flexibility.
Non-yellowing performance ensures superior clarity and aesthetic consistency in clearcoats and light-colored coatings.
Complies with major global regulatory standards for industrial coating systems, including REACH and VOC-compliant formulations.
Automotive OEM clearcoats and refinish topcoats.
High-performance industrial maintenance coatings for infrastructure and equipment.
Architectural and façade coatings requiring durability and aesthetic integrity.
Aerospace exterior protective coatings and primer-surfacer systems.
Plastic and composite part coatings demanding flexibility and adhesion without substrate stress.
