SQ-720007 PU Self-healing Fluid self-healing varnish uv curing resin for Invisible car coatings
SQ-720007 two-component specially modified PU self-healing fluid, mainly used for self-healing varnish on TPU and PVC. It can be applied by spraying, 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, does not produce rainbow streaks, has high cross-linking density, low curing shrinkage, and has extremely high weather resistance and self-healing properties. It can be used to make invisible car covers for cars and self-healing coatings for high-end electronic products.
