Aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI), offering excellent UV stability and color retention.
Low-viscosity trimer-type curing agent, enabling easy handling and compatibility with a wide range of polyol systems.
Provides outstanding chemical resistance, including resistance to hydrolysis, solvents, and abrasion in cured coatings.
Meets stringent VOC regulations due to its non-blocking, solvent-free formulation and low monomer content.
Enables fast ambient- or forced-dry curing with balanced pot life for industrial coating applications.
High-performance automotive clearcoats and basecoats requiring long-term gloss and weather resistance.
Industrial maintenance coatings for machinery, rail vehicles, and agricultural equipment.
Premium wood coatings for furniture, flooring, and architectural millwork.
Plastic coatings for electronics housings, sporting goods, and consumer appliances.
Two-component (2K) polyurethane topcoats in coil and sheet metal finishing lines.
