Environmental-Friendly Epoxy Curing Agent Solvent Free Low Viscosity HW-550M
Epoxy hardener HW-550M is a modified phenolic amine epoxy curing agent produced from cardanol. A functional curing agent with ultra-low temperature curing and promoting curing characteristics, at the same time with high solid, low viscosity, excellent mechanical properties, etc.;
When used alone, it can quickly improve the hardness of the paint film to achieve the effect of rapid polishing or use with other types of curing agent to improve the drying performance.
Performance
Environmental-friendly solvent free, low viscosity;
Good adhesion, flexibility, and other mechanical properties,
Ultra-low temperature fast curing, can quickly improve the hardness of the film to achieve the effect of rapid polishing.
Effectively improve the drying performance of other types of curing agents
