Highly reactive trimerized isocyanurate structure enabling rapid cure at ambient and elevated temperatures.
Excellent weather resistance and UV stability due to fully aliphatic backbone—no yellowing over time.
Low viscosity (150–250 mPa·s at 25°C) ensures easy handling, precise metering, and homogeneous blending with polyols.
Superior chemical resistance against solvents, acids, and alkalis in cured polyurethane coatings and elastomers.
Meets REACH and RoHS compliance requirements with no added solvents or heavy-metal catalysts.
High-performance two-component polyurethane topcoats for automotive OEM and refinish applications.
Durable protective coatings for industrial flooring, concrete sealers, and tank linings.
UV-stable elastomeric coatings used in architectural membranes and roofing systems.
Clear overcoats for wood finishes requiring gloss retention and scratch resistance.
Adhesives and sealants demanding fast fixture time and long-term flexibility.
