3, to improve the adhesion of the coating on the putty, the primer generally low viscosity, surface tension is slightly lower, fine particles, good fluidity, easy to penetrate into the putty surface, resulting in good adhesion;
4, the sealing effect, the primer can penetrate into the putty layer to fill the pores, can effectively prevent putty in the salt, alkali and other harmful substances with the evaporation of water to the paint film surface migration, affect the topcoat surface effect and the overall performance of the paint film .
