VAE emulsion is a polymer emulsion made by copolymerizing vinyl acetate and ethylene monomers with other auxiliary materials through emulsion polymerization. When the vinyl acetate content is in the range of 70% to 95%, it is usually in an emulsion state, called VAE emulsion. VAE emulsion has a milky white or slightly yellow appearance. VAE emulsion is mainly used in adhesives, coatings, cement modifiers and paper processing, and has many excellent properties.
