Highly reactive aliphatic isocyanate-based curing agent for fast ambient- and low-bake-cure systems.
Excellent weatherability and UV resistance due to aliphatic structure—ideal for exterior applications.
Low viscosity enables easy handling, precise metering, and superior compatibility with common hydroxyl-functional resins.
Non-yellowing performance ensures long-term gloss and color retention in clearcoats and pigmented coatings.
Complies with major global VOC regulations when formulated appropriately; supports low-VOC coating design.
Automotive OEM clearcoats and topcoats requiring high durability and gloss stability.
Industrial maintenance coatings for bridges, steel structures, and architectural facades.
High-performance plastic coatings for automotive trim and electronic housings.
Premium wood finishes demanding clarity, hardness, and resistance to abrasion and solvents.
Railway and bus exterior coatings where long-term color fidelity and chalking resistance are critical.
