Acrylic resin is a resin formed by copolymerization of acrylic ester and methyl methacrylate and other olefinic monomers. By selecting different resin structures, different formulations, production processes and solvent compositions, acrylic resins of different types, different properties and different uses can be synthesized. According to different structures and film-forming mechanisms, acrylic resin can be divided into thermoplastic acrylic resin and thermosetting acrylic resin. The main absorption peak of acrylic resin synthesized by copolymerization of acrylate and methacrylate monomer is outside the range of solar spectrum, so the acrylic resin coating has excellent light resistance and outdoor aging performance. Thermoplastic acrylic resin will not be further crosslinked during film forming process, so its relative molecular weight is larger, it has good light and color retention, water resistance and chemical resistance, fast drying, convenient construction, easy to recoat and rework, and aluminum powder prepared by aluminum powder has high whiteness and good positioning. Thermoplastic acrylic resin is widely used in automobile, electrical appliances, machinery, construction and other fields. Thermosetting acrylic resin refers to a functional group in the structure, which forms a network structure by reacting with the added amino resin, epoxy resin, polyurethane and other functional groups in the coating. The molecular weight of thermosetting resin is relatively low. The thermosetting acrylic coating has excellent fullness, glossiness, hardness, solvent resistance, weather resistance, no discoloration and no yellowing when baking at high temperature. The most important application is to manufacture amino-acrylic coating with amino resin, which is widely used in automobiles, motorcycles, bicycles, coil steel and other products. According to production mode, it can be divided into: 1. lotion polymerization is the reactive polymerization of monomer, initiator and reaction solvent. Generally, the solid content of resin is 50% of the resin solution! It is a solvent resin containing about 50%, which generally reacts with the solution of benzene (toluene or xylene), ester (ethyl acetate, butyl acetate), generally single or mixed! Solid lotion acrylic resin is solvent invariant! Generally, the solvent selection and product performance are different! It usually has a certain color number! The glass transition temperature is low because the reaction is usually carried out without methyl acrylate! Solids This type of resin can have a higher solid content, up to 80%! It can be used as high solid coating, and the production is simple! However, due to the invariability of solvent, transportation is not convenient! 2. Suspension polymerization is a relatively complex production process, which is generally used to produce solid resin! Solid acrylic resin, which is usually polymerized downward with methyl acrylate! Acrylates without methyl group...

This is first international coating show after reopening of China's borders. This Coating show has provided an international platform for coatings and ink industry suppliers and manufacturers to connect with global trade visitors, particularly from the China and Asia-Pacific region. In this exhibition, we met some old customers and investigated market demand. It is good chance to us. Looking forward to seeing you next Chinacoat in Shanghai this year.

Cellulose acetate butyrate (CAB) is a thermoplastic cellulose ester with a butyryl content of 30-55 % by weight. It is the most commercially important blended cellulose ester, with many attractive properties such as low viscosity, high clarity and surface gloss, improved resistance to moisture and ultraviolet (UV) light, and excellent intercoating adhesion. CAB is compatible with many resin systems, including most acrylates, polyesters, phenols, ureas, and isocyanates. However, they are generally incompatible with melamine, urea-aldehydes, and many alkynes. Both solubility and miscibility depend on the butyl-group content; Generally, solubility in many resins and solvents increases with increasing butylyl content. For example, CAB resins with high butylyl content are soluble in many mixtures of esters, ketones, glycol ethers, alcohols, and aromatic hydrocarbons. CAB is commonly used in coating formulations that require low application viscosity at relatively high solids content. When added to a coating formulation, it enhances many of the properties of the coating, such as hardness, leveling, solvent resistance, clarity and shine, while reducing dry contact time, pitting, orange streaks and blocking. Because of CAB's superior property, it has many uses in coatings, including metal and wood coatings, gravure and flexographic inks, graphic art, inkjet printing inks, nail paint topcoats, automotive varnishes and primers, and general industrial coatings.
