Application field of epoxy resin

Epoxy resin has excellent physical, mechanical and electrical insulation properties, bonding properties with various materials, as well as the flexibility of its use process, which is not possessed by other thermosetting plastics.Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, in various fields of the national economy has been widely used.

(1) coating

Epoxy resin in the application of coatings accounted for a larger proportion, it can be made into various characteristics, different uses of varieties.Its commonality: (1) excellent chemical resistance, especially alkali resistance.(2) Strong adhesion of paint film, especially to metal.(3) With good heat resistance and electrical insulation.(4) The paint film has good color retention.

However, bisphenol A epoxy resin coating has poor weather resistance, and the film is easy to powder and lose luster in outdoor, so it is not suitable for outdoor coating and high decorative coating.Therefore, epoxy resin coating is mainly used as anti-corrosion paint, metal primer, insulating paint, but heterocyclic and alicyclic epoxy resin coating can be used outdoors.

(2) adhesive

Epoxy resin not only has poor adhesion to polyolefin and other non-polar plastics, but also has poor adhesion to various metal materials such as aluminum, steel, iron and copper.Non-metallic materials such as glass, wood, concrete, etc.As well as thermosetting plastics such as phenolic, amino, unsaturated polyester and so on have excellent bonding performance, so it is known as all-purpose glue.Epoxy adhesive is an important kind of structural adhesive. The raw material of Kelin tile grout supplier products is epoxy resin.

(3) Electronic and electrical materials

Epoxy resin has been widely used in the insulation and packaging of high and low voltage electrical appliances, motors and electronic components due to its many unique advantages such as high insulation performance, high structural strength and good sealing performance.

(4) Engineering plastics and composite materials

Epoxy engineering plastics mainly include epoxy moulding plastics, epoxy laminating plastics and epoxy foam plastics used for high pressure molding.Epoxy engineering plastics can also be regarded as a generalized epoxy composite material.Epoxy composite materials mainly include epoxy glass fiber reinforced plastics (general type composite materials) and epoxy structural composite materials, such as pultrusion shaped epoxy profiles, winding shaped hollow rotary products and high-performance composite materials.Epoxy composite is an important structural and functional material in chemical industry, aviation, aerospace, military and other high-tech fields.

The epoxy resin used in the products of Kelin epoxy gap filler manufacturer is more environmentally friendly and healthy. Welcome to contact us in the decoration of the owners.
