Thick coating type PE clear primer

Abstract

The invention provides a thick coating type PE clear primer. The thick coating type PE clear primer comprises a component A, a component B, a component C and a component D, wherein the component A iscomposed of, in parts by weight, 65 to 75 parts of unsaturated polyester resin, 2 to 3 parts of polyether resin, 0.2 to 0.3 part of a dispersing agent, 18 to 25 parts of a filling agent, 0.3 to 0.5 part of an antifoaming agent, 0.3 to 0.5 part of a leveling agent, 0.1 to 0.2 part of an anti-greening agent and 3 to 5 parts of an unsaturated solvent; the component B is a diluent; the component C isketone peroxide; and the component D is a curing accelerator. By adopting the combination of the unsaturated polyester resin and polyether resin, the coating has the advantages of favorable sinking resistance, favorable transparency, high filling property, no cracking and the like, and can be widely used for primer coating of high-grade solid wood and customized furniture.
