Acrylic resin refers to a copolymer formed from a series of radical polymerization reactions of acrylate or methacrylate. Acrylic resins with different properties can be synthesized by changing the resin content, resin structure and processing method.
Due to the advantages of rich variety and excellent performance, acrylic resin has a very wide range of applications in the fields of coatings, textile printing and dyeing, photoresistance reagents and pharmaceuticals.
- Coating: Acrylic resin, with excellent weather resistance, heat resistance and corrosion resistance, is a very good film-forming material, and has a very great application value in the field of coatings. Acrylic resins are commonly used as latex paints, exterior paints, self-spray paints, UV-curable paints, and powder paints in the paint field. For example, latex paint is currently the largest amount of paint on the decoration market. It has a large proportion of water and is a decorative coating with low VOC content, ecological health, safety and environmental protection. Waterborne acrylic resin is one of the key raw materials for the production of latex paints, and is often used as a film-forming substance in industry.

- Textile: Some types of acrylic resin have the characteristics of light color, color retention, gloss retention, weather resistance, corrosion resistance and pollution resistance, and the products produced have low temperature requirements, so they are widely used in the textile industry. For example, a class of acrylic resins can be made using acrylate, methacrylate and styrene as the main raw materials. All properties and characteristics of this acrylic resin are suitable for textile printing and dyeing operations in the textile industry.

- Photoresist: Photoresist is widely used in microelectronics manufacturing, screen printing, printed circuit boards, color filters, etc. Acrylic resin is often used as a film-forming substance for photoresistance agents due to its advantages of high transparency and simple synthesis process. For example, acrylates with pendant adamantane groups have the advantages of high light transmittance and good corrosion resistance, and pendant adamantane groups become carboxyl groups after exposure under the catalysis of photoacid generators, and therefore are widely used 193 nm positive photoresist.
- Other fields: In addition to the above-mentioned fields, acrylic resin has extensive applications in other fields. 3D printing technology has been used in many industries such as medical and medical, construction and industrial mold. At present, the commonly used 3D printing materials are mainly gypsum powder after special treatment. When gypsum powder is used alone as a 3D printing material, the adhesion of the printed product is low. Adding acrylic acid as an adhesion aid can improve the bonding ability of gypsum powder, so as to obtain 3D printing materials with good performance. In addition, acrylic resin can be used as an auxiliary material to play an important application value in the field of medicine. At present, acrylic resins have been used in various coatings for pharmaceutical preparations, sustained-release matrix materials and matrix adhesive materials for transdermal formulations.

According to different classification methods, acrylic resins can be divided into different types. For example, according to different production methods, acrylic resin can be divided into emulsion polymerized acrylic resin, suspension polymerized acrylic resin and bulk polymerized acrylic resin. According to different structures and film-forming mechanisms, acrylic resins can be divided into thermoplastic acrylic resins and thermosetting acrylic resins. According to the different fractional media, acrylic resin can be divided into oily acrylic resin and water-based acrylic resin.
