The excellent physical and mechanical properties of epoxy resins, the bonding properties with various materials, and the flexibility of their use are not available in other thermoset plastics. Therefore, it can be used in coatings, composites, castings, adhesives, molded materials and injection molding materials, and is widely used in various fields of the national economy.
First, the paint
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. Commonality:
1. Excellent chemical resistance, especially alkali resistance. 2. The paint film has strong adhesion, especially to metal.
3. Has good heat resistance and electrical insulation.
4. The paint film has good color retention.
However, the bisphenol A type epoxy resin coating has poor weather resistance, and the paint film is easy to be powdered and lost in the outdoor, and is not suitable for outdoor coatings and high decorative coatings. Therefore, epoxy resin coatings are mainly used as anticorrosive paints, metal primers, and insulating paints, but coatings made of heterocyclic and cycloaliphatic epoxy resins can be used outdoors.
Second, the adhesive
In addition to poor adhesion to non-polar plastics such as polyolefins, epoxy resins are used 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 universal adhesive. Epoxy adhesives are an important variety of structural adhesives.
