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. It is designed for basecoats, topcoats and clearcoats on various metal substrates.
Features: Excellent compatibility with solvent-based isocyanate curing agents, fast hardness increase,high bubble-free limit film thickness, good chemical resistance

Applications
When used with solvent-based isocyanate curing agent, it needs to be diluted to 60-70% with a suitable co-solvent such as BGA, PGDA or PMA+DBE (1:2) before use. At the same time, the main agent and curing agent need to be fully stirred after mixing. The ideal mixing method is to mix with a pneumatic or electric stirrer. The water dilution rate should not be too high. It is generally recommended to add 5% of the main agent and no more than 10% at most, otherwise the gloss may decrease.
