L-2960 Self-repairing PU resin Invisible car coating film has self-healing function heated curing
L-2960 is a specially modified PU resin. After cross-linking reaction with isocyanate, an interpenetrating network structure system is formed. After mixing, toughness and plasticity of base material are outstanding. After drying and film formation, scratches on the surface will not cause a fracture response, and it has good scratch resistance and quick repair effects. The paint film has the characteristics of good fullness, good aging resistance, good anti-fouling performance, and automatic repair function. It is very suitable for high-requirements automotive protective films, automotive interior parts, protective coatings for motorcycle helmets and other fields.
