Use | Acrylic Emulsion is used as an adhesive, compared with other adhesives, it is particularly excellent in weather resistance and aging resistance, and has high adhesive strength, good water resistance, large elasticity and high elongation at break. Therefore, it is widely used in pressure sensitive adhesives, fabric printing and dyeing adhesive, electrostatic adhesive, paper glue, etc. |
polyacrylic acid-based copolymer emulsion. It is generally based on methyl acrylate and other acrylic acid low Ester organic compounds as the main monomer, and acrylonitrile, styrene, dibutyl maleate, methacrylate, vinyl chloride, vinylidene chloride or vinyl acetate copolymerization. Functional monomers, such as (meth) acrylic acid, maleic acid, fumaric acid, (meth) acrylamide, and the like, are sometimes introduced in order to impart certain specific properties to the polymer emulsion.
