Highly reactive aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) trimer.
Excellent weather resistance and UV stability — ideal for outdoor applications requiring long-term gloss and color retention.
Low volatility and low monomer content, supporting safer handling and compliance with VOC regulations.
Good compatibility with a wide range of hydroxyl-functional resins including polyesters, acrylics, and polyethers.
Enables formulation of high-performance two-component (2K) polyurethane coatings with balanced pot life and rapid cure development.
Automotive OEM and refinish clearcoats and basecoats.
Industrial maintenance coatings for machinery, rail, and agricultural equipment.
High-end architectural coatings for façades, windows, and metal cladding.
Plastic coatings for automotive interior trim and consumer electronics housings.
Wood coatings for premium furniture and flooring requiring durability and aesthetic clarity.
