[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of silicone acrylic emulsion, is silicone acrylic emulsion dangerous goods?

Properties of silicone-acrylic emulsion

Silicone-acrylic emulsion (Silicone Acrylic Emulsion) is an emulsion formed by the copolymerization of silicone resin and acrylic resin. It combines the weather resistance of silicone resin with the excellent film-forming properties of acrylic resin, and has excellent physical and chemical properties. Silicone acrylic emulsion has good water resistance, weather resistance and UV resistance, not easy to yellowing, but also has high flexibility and adhesion. These characteristics make it widely used in coatings and adhesives. The low volatile organic compound (VOC) content of silicone acrylic emulsion makes it meet the requirements of environmental protection and become one of the representatives of green environmental protection materials.

The use of silicone acrylic emulsion

Because of its unique properties, silicone-acrylic emulsion has been widely used in many fields. In the construction field, silicone-acrylic emulsion is often used as exterior wall coatings and waterproof coatings, which can effectively improve the durability and aesthetics of buildings. In industrial coatings, silicone-acrylic emulsion is used for protective coatings on metal and wood surfaces to provide good corrosion and aging resistance. Silicone-acrylic emulsion is also used in paper coating, textile treatment and leather finishing to enhance the added value and performance of products.

Upstream raw materials

The main upstream raw materials for the production of silicone-acrylic emulsions include silicone resins, acrylic monomers and their esters, emulsifiers, initiators and other auxiliary additives. The silicone resin is composed of a silicone polymer and has excellent heat resistance and weather resistance. Acrylic acid and its ester monomers are the basis for the production of acrylic resins and form high molecular polymers through free radical polymerization. Emulsifiers are used to stabilize the emulsion system so that it remains uniformly dispersed. The initiator plays a starting role in the polymerization reaction and promotes the polymerization of the monomer. According to specific application requirements, various functional additives, such as ultraviolet absorbers, plasticizers, etc., can also be added to improve the performance of the emulsion.

Downstream Products

Silicone acrylic emulsion has a wide range of downstream products, covering a number of industrial and consumer areas. In the coating industry, silicone-acrylic emulsion is used as a base material for various functional coatings, such as waterproof coatings, anti-corrosion coatings and decorative coatings. In the field of adhesives, silicone-acrylic emulsions can be made into high-performance adhesives for construction, electronics and automotive industries. Silicone acrylic emulsion is also widely used in the processing of textiles, paper and leather to improve product performance and service life. With the progress of science and technology and the changing market demand, the application fields and product types of silicone acrylic emulsion are also expanding and upgrading.

Silicone-acrylic emulsion storage method

During the storage of silicone-acrylic emulsion, attention should be paid to prevent freezing and thawing and long-term exposure to high temperature environment. Under normal circumstances, silicone-acrylic emulsion should be stored in a cool, dry and well-ventilated warehouse, avoiding direct sunlight and high temperature heat sources. The storage temperature is generally controlled between 5°C and 35°C to ensure the stability and performance of the emulsion. Storage containers shall be well sealed to prevent contamination and evaporation of water. In the use of the process, should try to avoid long-term exposure to the air, in order to prevent the formation of film on the surface of the emulsion or agglomeration phenomenon.

Market demand and development trend

With the enhancement of environmental awareness and technological progress, the market demand for silicone-acrylic emulsion is growing. Especially in the fields of construction, automotive and consumer electronics, the demand for high-performance, environmentally friendly coatings and adhesives continues to increase. In the future, with the development of more new functional monomers and additives, the performance of silicone-acrylic emulsion will be further improved, and the application field will be more extensive. The development trend of green environmental protection materials will promote the application of silicone acrylic emulsion in more emerging markets, such as biodegradable materials and smart coatings.

Competitive Situation and Industry Prospects
