TY-701 Water-based blocked polyisocyanate curing agent

TY-701 is a water-based blocked polyisocyanate curing agent, which can be quickly unblocked at 120°C and can be used as an internal addition crosslinking agent is added to the water-based resin as a one-component system. It can be stored for a long time at room temperature and heated to 120°C and above, the unblocking and cross-linking begins, which can significantly improve the water resistance, heat resistance, abrasion resistance, and chemical resistance of the paint film. It can improve the comprehensive properties of coating and salt spray resistance , and at the same time enhance the adhesion to the substrate.
