SQ-720001 One-component UV light hardening liquid, mainly used for hardening the surface of PC, PET, PMMA, PC/PMMA composite sheet or film. It can be coated by spraying, curtain coating, roller coating, etc. After the coating is formed into a film, it has good adhesion to the substrate and can protect the surface of the coated material for a long time. The coating process is simple and the production efficiency is high. The coating has good optical properties, no rainbow pattern, high cross-linking density, low curing shrinkage, extremely high hardness and excellent wear resistance. It can be used to make texture decoration and shell molding of mobile phones, notebook computers, home appliances and other products. High hardness, good chemical resistance, high transparency, steel wool resistance 30-80 times.
