Highly stable blocked isocyanate based on IPDI trimer, offering excellent shelf life and handling safety at ambient temperatures.
Enables low-bake curing (typically 120–140 °C), supporting energy-efficient coating processes without compromising film performance.
Delivers outstanding weather resistance, gloss retention, and UV stability in demanding outdoor applications.
Provides superior chemical resistance and mechanical durability, including hardness, flexibility, and abrasion resistance.
Compatible with a broad range of hydroxyl-functional resins (e.g., acrylics, polyesters, alkyds) for versatile formulation flexibility.
Automotive OEM and refinish clearcoats requiring high gloss, mar resistance, and long-term durability.
Industrial maintenance coatings for metal substrates exposed to harsh environmental or chemical conditions.
Architectural coil coatings where color stability, chalking resistance, and rapid line speed are critical.
Plastic coatings for automotive interior and exterior trim components.
Powder coating hybrid systems seeking enhanced flow, leveling, and edge coverage.
