Highly stable blocked isocyanate based on hexamethylene diisocyanate (HDI) with methyl propyl amine (MPA) blocking agent.
Excellent storage stability at ambient temperature with low volatility and minimal risk of premature deblocking.
Enables one-component (1K) polyurethane formulations with controlled thermal curing onset around 120–140 °C.
Delivers superior film hardness, flexibility, and chemical resistance in cured coatings.
Compatible with hydroxyl-functional acrylics, polyesters, and polyols for high-performance industrial coatings.
Automotive OEM and refinish clearcoats requiring high gloss and durability.
Industrial maintenance coatings for metal substrates including machinery and agricultural equipment.
Plastic coatings for automotive interior trim and consumer electronics housings.
Wood coatings for premium furniture and flooring requiring low-temperature cure capability.
Coil coatings where balanced crosslink density and processing safety are critical.
