Bifunctional aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) trimer chemistry.
Low-viscosity liquid with excellent storage stability and reduced tendency for gelation.
Offers outstanding UV resistance and long-term color stability in coated systems.
Compatible with a broad range of hydroxyl-functional resins including polyesters, acrylics, and polyethers.
Enables fast ambient- or forced-dry curing with balanced pot life and film formation.
High-performance automotive clearcoats and basecoats requiring gloss retention and weatherability.
Industrial maintenance coatings for metal and plastic substrates exposed to outdoor conditions.
Architectural coatings for façade systems and aluminum composite panels (ACPs).
Precision coatings for optical lenses and electronic enclosures demanding low yellowing.
Wood finishing systems where clarity, hardness, and chemical resistance are critical.
