Highly reactive aliphatic isocyanate-based curing agent for fast ambient- and low-bake-cure systems.
Excellent compatibility with hydroxyl-functional acrylics, polyesters, and polyester-acrylic hybrids.
Low viscosity enables easy handling, precise metering, and improved formulation stability.
Provides superior gloss retention, weather resistance, and mechanical durability in finished coatings.
Meets stringent VOC regulations with minimal monomeric HDI content and no added solvents.
Automotive OEM clearcoats and basecoats requiring high-speed production line cure.
Industrial maintenance coatings for metal substrates exposed to outdoor environments.
High-performance plastic coatings for automotive trim and electronic housings.
Powder coating hybrid systems where liquid curing agents enhance flow and film formation.
