Product introduction
Epoxy resin
Epoxy resin is a kind of polymer, the molecular formula is (C11H12O3)n, which refers to a class of polymers containing more than two epoxy groups in the molecule. It is A condensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, it can be opened by a variety of compounds containing active hydrogen, curing crosslinking to form a network structure, so it is a thermosetting resin. Bisphenol A type epoxy resin not only has the largest yield and the most complete variety, but also the new modified varieties are still increasing, and the quality is constantly improving.

Product application
The excellent physical mechanical and electrical insulation properties of epoxy resin, the bonding properties with various materials, and the flexibility of its use process are not available to other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and has been widely used in various fields of the national economy.
Coating application
The application of epoxy resin in coatings accounts for a large proportion, and it can be made into various varieties with different characteristics and uses. Its commonalities:
1. Excellent chemical resistance, especially alkaline resistance.
2. The film has strong adhesion, especially to metals.
3. It has good heat resistance and electrical insulation.
4. The paint film has good color retention.
However, bisphenol A type epoxy resin coating has poor weather resistance, and the paint film is easy to powder and lose light and lack fullness in the outdoors, so it is not suitable for outdoor coating and high decorative coating. Therefore, epoxy resin coatings are mainly used as anti-corrosion paints, metal primers, insulating paints, but heterocyclic and alicyclic epoxy coatings can be used outdoors.
Adhesive use
In addition to poor adhesion to non-polar plastics such as polyolefin, epoxy resin is suitable for various metal materials such as aluminum, iron and copper; Non-metallic materials such as glass, wood, concrete, etc.; And thermosetting plastics such as phenolic, amino, unsaturated polyester, etc. have excellent bonding properties, so they are known as versatile adhesives. Epoxy adhesive is an important type of structural adhesive.
