Epoxy resin has excellent physical mechanical and electrical insulation properties, adhesion to various materials, and flexibility in its use process that other thermosetting plastics do not have. Therefore, it can be made into coatings, composite materials, casting materials, Adhesives, molding materials and injection molding materials are widely used in various fields of the national economy. Below we will explain in detail the application areas of epoxy resins.
The application of epoxy resin in coatings accounts for a large proportion, and it can be made into varieties with different characteristics and different uses.
In addition to poor adhesion to non-polar plastics such as polyolefins, epoxy resins are suitable for various metal materials such as aluminum, steel, iron, 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 it is called glue. Epoxy adhesive is an important variety of structural adhesives.
3. Electronic and electrical materials
Because of its many unique advantages such as high insulation performance, high structural strength and good sealing performance, epoxy resin has been widely used in the insulation and packaging of high and low voltage electrical appliances, motors and electronic components, and has developed rapidly.
4. Engineering plastics and composite materials
Epoxy engineering plastics mainly include epoxy molding plastics and epoxy laminated plastics used for high-pressure molding, as well as epoxy foam plastics. Epoxy engineering plastics can also be regarded as a broad sense of epoxy composite materials. Epoxy composite materials There are mainly epoxy glass fiber reinforced plastics (universal composite materials) and epoxy structural composite materials, such as pultruded epoxy profiles, wound hollow hollow products and high-performance composite materials. Epoxy composite materials are chemical and aerospace , Military industry and other high-tech fields of an important structural material and functional materials.
5. Civil engineering materials
Mainly used as anti-corrosion floors, epoxy mortar and concrete products, high-grade pavement and airport runways, quick repair materials, grouting materials to strengthen foundations, construction adhesives and coatings, etc.
