Highly reactive blocked isocyanate based on HDI (hexamethylene diisocyanate) with excellent storage stability.
Enables one-component (1K) polyurethane systems with low-temperature curing capability (typically 120–140 °C).
Delivers outstanding film hardness, chemical resistance, and weathering performance in final coatings.
Low volatility and minimal blocking agent emission during cure, supporting VOC-compliant formulations.
Excellent compatibility with hydroxyl-functional acrylics, polyesters, and alkyds for broad formulation flexibility.
Automotive OEM and refinish topcoats requiring high-gloss, durability, and rapid throughput.
Industrial maintenance coatings for metal substrates exposed to harsh environmental conditions.
Coil coatings demanding excellent formability, corrosion resistance, and bake efficiency.
Powder coating hybrid systems where enhanced crosslink density and surface quality are critical.
General-purpose high-performance 1K thermosetting coatings for appliances and architectural metal.
