Polyurethane acrylate

RU-637B
  • RU-637B
RU-637B
Features:Six functional PUA resin, with high reactivity and low viscosity, has excellent solvent resistance, scratch resistance, and wear resistance in cured coatings. It has high hardness, appropriate flexibility, and good resistance to yellowing and weathering. It has excellent adhesion performance to various plastic substrates such as PC and ABS, and can achieve good adhesion even when used alone. It also has good adhesion performance to substrates such as paper, wood, and metal.
