Acrylic emulsions are widely used in the coating industry. They are polymer emulsions mainly composed of acrylic monomers such as methyl acrylate, butyl acrylate, and acrylic acid. These emulsions have excellent weather resistance, good adhesion to various substrates, and can provide coatings with high gloss and good color retention. For example, acrylic emulsions can withstand long-term exposure to sunlight, rain, and other environmental factors without significant yellowing or peeling in exterior wall coatings.
