Low-viscosity liquid MDI-based polyisocyanate offering excellent processability in ambient-cure and heat-cure systems.
Contains no added solvents — supports VOC-compliant formulations and sustainable manufacturing practices.
Provides balanced reactivity for controlled pot life and efficient film formation in two-component polyurethane coatings.
Delivers outstanding chemical resistance, hardness, and gloss retention in demanding industrial finishes.
Compatible with a broad range of polyols including polyester, acrylic, and polyether types.
Industrial maintenance coatings for metal substrates (e.g., machinery, storage tanks, structural steel).
High-performance automotive refinish clearcoats and basecoat/clearcoat systems.
Wind turbine blade protective coatings requiring UV stability and erosion resistance.
Railway vehicle exterior and interior coating systems meeting fire-safety standards (e.g., EN 45545).
General-purpose two-component polyurethane topcoats for architectural and infrastructure applications.
