Suzhou Epoxy Resin Industry Association experts recently been devoted. Increased use of such additives will reduce the surface tension of the coating film formation which is conducive to self-leveling coating and foaming. Cement mortar substrate within which there are many pores displace the air is left in the film coating, in order to guarantee a fine, improve dispersion efficiency class also joined dispersing aids, all additives are added to improve the construction and improving the performance epoxy coating for the purpose of considering the selection of wear-resistant surface coatings should Suzhou Epoxy Industry Association experts said, leveling agents should use acrylic copolymers, can migrate to the film surface in a short time to form a monolayer, homogenization of the surface tension and reduce the surface tension gradients caused by various coating surface defects.
