The main application field of epoxy resin

Epoxy resin excellent physical and mechanical and electrical insulating properties, and all kinds of adhesive performance, and its use of materials of flexibility is what other thermosetting plastic does not have. Because it can make the coating, composite materials, casting materials, adhesives, moulding materials and injection molding materials, in the national economy has been widely used in various fields.

1) coating represents a significant proportion of the application of epoxy resin in coatings, it can make use of different varieties and distinctive. Its universality:

( 1) Good chemical resistance, alkali resistance in particular.

　　( 2) Film adhesion strong, especially in metal.

　　( 3) Has good heat resistance and electrical insulation.

　　( 4) Film color retention is better.

but poor weatherability of bisphenol A type epoxy resin coating, paint film easily pulverization lost in the outdoor light owed plump, high unfavorable for outdoor coatings and decorative coatings. Therefore epoxy resin coatings are mainly used as anticorrosive paint, metal primer, insulating paint, but heterocyclic and alicyclic epoxy resin coatings can be used in outdoor.

　　( 2) It is widely used in electronic components and wiring devices of the potting insulation. Has become indispensable to the electronics industry important insulation.

　　( 3) Electronic level of epoxy molding compound used in the semiconductor components encapsulation. Their fast in recent years. Because of its superior performance, to replace the traditional metal, ceramic and glass packaging trends.

　　( 4) Epoxy laminate applied widely in the field of electronics, electrical appliances. With the development of epoxy resin copper clad especially rapidly, has become one of the basic materials of the electronic industry.

in addition, epoxy insulating coatings, adhesives and electrical insulating adhesives also has a large number of applications.

(4) engineering plastics and composite materials epoxy engineering plastics including used for high pressure molding epoxy molding compound and epoxy laminate, and epoxy foam plastics. Epoxy engineering plastics can also be regarded as a kind of generalized epoxy composite materials. Epoxy composite materials are mainly epoxy glass fiber reinforced plastic ( Universal composite material) And structure of epoxy composites, such as pultrusion epoxy profile, hollow of rotors of winding products and high performance composite materials. Epoxy composite materials is the chemical and aviation, spaceflight, war industry such as technology in the field of a kind of important structural materials and functional materials.

5) civil engineering material is mainly used as anticorrosive floor, epoxy mortar and concrete products, senior roads and airport runway, rapid repairing materials, and reinforce the foundation grouting materials, adhesives and coatings, etc.
