Aliphatic isocyanate based on isophorone diisocyanate (IPDI), offering excellent UV stability and color retention.
Low volatility and high functionality ensure improved pot life and controlled reactivity in two-component polyurethane systems.
Superior chemical resistance, especially to solvents, acids, and alkalis, enhancing coating durability in aggressive environments.
Enables formulation of high-performance, glossy, and scratch-resistant topcoats for demanding industrial applications.
Compatible with a broad range of polyols—including polyester, acrylic, and polyether—supporting flexible resin design.
High-end automotive clearcoats and basecoats requiring long-term gloss and weather resistance.
Industrial maintenance coatings for machinery, steel structures, and offshore equipment.
Wind turbine blade coatings exposed to extreme UV, moisture, and mechanical stress.
Precision optical and electronic encapsulation systems where clarity and adhesion are critical.
Aerospace interior coatings meeting stringent VOC, fire, smoke, and toxicity (FST) requirements.
