Product Introduction
It is a water-based hydroxylated acrylic dispersion, which is
recommended to be used with solvent- based or water-based
isocyanate curing agents to prepare water-based high-performance
two- component polyurethane coatings, designed for topcoats on
various metal substrates.
The resin has a hydroxyl content of WEI 3.9%, which is particularly
suitable for construction environments with high temperature and
low humidity. It can be used with an oily curing agent, which has a
better cost-effectiveness.
Features: Excellent compatibility with solvent-based isocyanate
curing agents, excellent water resistance, and long application
period.
