High chemical resistance to solvents, acids, and alkalis due to symmetric hexamethylene diisocyanate (HMDI) structure.
Excellent UV stability and color retention, making it ideal for outdoor and light-exposed applications.
Low volatility and low vapor pressure, enhancing workplace safety and reducing VOC emissions during processing.
Controlled reactivity with hydroxyl-terminated resins, enabling precise pot-life management and smooth film formation.
Superior mechanical performance in cured films, including high hardness, abrasion resistance, and flexibility balance.
High-performance polyurethane coatings for automotive OEM and refinish systems.
Durable clearcoats and topcoats for industrial wood and metal finishing.
UV-resistant elastomeric coatings for architectural membranes and roofing systems.
Advanced adhesives and sealants requiring long-term weatherability and thermal stability.
Specialty inks and overprint varnishes for flexible packaging demanding food-contact compliance.
