Epoxy resin- Intro

Epoxy resin’s excellent electrical insulation and adhesive properties of various materials, as well as the flexibility to other thermosetting plastics, are not available. So it made paint, composite materials, casting materials, adhesives, molding materials and injection molding materials, which have been widely applied in all areas of the national economy. First, paint Checkout epoxy for more info.

Epoxy resin accounts for a large proportion in coatings, which are in common:

1, excellent chemical resistance, particularly alkali.

2, the film adhesion, especially for metal.

3, good heat resistance and electrical insulation.

4, good paint and color retention.

However, bisphenol A epoxy resin coating and poor weather are easy to powder coating and not suitable for outdoor use. Therefore it is mainly used for anti-corrosion epoxy coating paint, metal primer and varnish, but the heterocyclic and alicyclic epoxy resin coating can be made outdoors.

Second, adhesive

A variety of metal materials such as aluminum, steel, iron, copper;non-metallic materials such as glass, wood, concrete, etc; thermosetting plastics such as phenolic, amino, unsaturated polyester all have excellent adhesive properties. Structural adhesive epoxy adhesive is an important species.

Third, electrical and electronic materials

As epoxy resin has many unique advantages like high insulation performance, high structural strength and sealing performance. It has widely applied and developed rapidly in high and low voltage electrical appliances, electrical and electronic components and packaging of insulation. Mainly used for:

1, Electrical appliances, electrical insulation package, casting parts. Such as solenoid, contactor coils, transformers, dry type transformer high-voltage electrical insulation package, the whole sealed parts. In the electrical industry it has developed rapidly. It has been developed from the pressure casting and vacuum casting to the automatic pressure gel.

2, It is widely used in electronic components and circuit encapsulation device, which has become an important and indispensable insulating material in electronics industry.

3, Electronic grade epoxy molding compounds are used for semiconductors in recent years. Because of its superior performance, much trends to replace the traditional metal, ceramic and glass packaging.

4, Epoxy laminated plastic has a wide range in the electronic and electrical field. Particularly epoxy laminate with rapid development has become one of the basic materials of electronic industry.
