What is Water-based acrylic Emulsion? How is water-based acrylic emulsion classified? Water-based acrylic emulsion is a type of emulsion that is produced by emulsion polymerization, in which various monomers of acrylic acid are polymerized. This emulsion is widely used in the coatings, adhesives, paper, and textile industries. The production process can be simply described as follows: First, mix part of the acrylic acid monomers, then add them to water that has been dissolved with an emulsifier and stirred at high speed to form an emulsion. Then, add the initiator and heat the mixture to a certain temperature for polymerization reaction. Gradually add the remaining monomers for polymerization, and finally add the chain transfer agent to terminate the reaction to produce acrylic emulsion. Water-based acrylic emulsion has high gloss, fast drying, water resistance, oil resistance, and heat resistance properties. These properties make it excel in various application scenarios.
