High-reactivity aliphatic isocyanate based on hexamethylene diisocyanate (HDI) trimer chemistry.
Excellent weather resistance and UV stability, preventing yellowing in outdoor applications.
Low viscosity enables easy handling, precise metering, and homogeneous mixing with hydroxyl-functional resins.
Non-yellowing performance suitable for clearcoats and light-colored coating systems.
Compliant with major global VOC regulations and formulated for low-monomer content (<0.1% free HDI).
Automotive OEM clearcoats and basecoat/clearcoat systems.
High-performance industrial maintenance coatings for machinery and infrastructure.
Premium architectural coatings requiring long-term gloss retention and color stability.
Plastic coatings for automotive interior trim and consumer electronics housings.
UV-resistant wood finishes for premium furniture and flooring applications.
