Water-based acrylic resins: include acrylic resin emulsions, acrylic resin water dispersions (also known as water-dilutable acrylics), and acrylic resin aqueous solutions. Emulsions are mainly synthesized by emulsifying oily olefin monomers in water and initiating them with water-based free radical initiators, while resin water dispersions are synthesized through different processes such as free radical solution polymerization or step-growth solution polymerization. Acrylic emulsions are mainly used as the base material for emulsion paints and occupy an important application in the architectural coatings market, and their applications are continuously expanding; in recent years, the development and application of acrylic resin water dispersions have attracted increasing attention, and their applications in industrial and civil coatings are continuously expanding. According to the monomer composition, they are usually divided into pure acrylic emulsions, styrene-acrylic emulsions, vinyl acetate-acrylic emulsions, silicone-acrylic emulsions, tertiary acetate (tertiary carbonate-vinyl acetate) emulsions, and tertiary acrylic (tertiary carbonate-acrylate) emulsions, etc.

 

　　Water-based polyurethane resin: is an extremely fine aliphatic polyurethane dispersion. It is mainly used to enhance the adhesion of coatings, has an ultra-fine and extensible film, and excellent cold resistance, but will not overfill the particle surface. Specially designed for substrate adhesive layers. Water-based polyurethane resin is often used in adhesive layers and can be added at 20-30% of the resin amount, combined with other resins to adjust the hardness and softness of the coating.
