Waterborne polyurethane topcoat

Basic parameters

Waterborne polyurethane topcoat is a kind of coating with waterborne polyurethane resin as the base material and water as the dispersion medium. It has the advantages of low production cost, non-flammable, non-toxic, no pollution to the environment, saving organic solvent and so on. In addition, it also retains some excellent properties of traditional solvent-based polyurethane coatings, and has good adhesion to wood, fiberboard, metal, concrete and so on. Compared with solvent-based polyurethane resin, it has low toxicity and excellent color retention.
