Introduction to Epoxy Resin

           Epoxy resin is a kind of polymer, the molecular formula is (C11H12O3)n, which refers to a class of polymers containing more than two epoxy groups in the molecule. It is A condensation product of epichlorohydrin and bisphenol A or polyol.

Properties

1.The hardening shrinkage rate of epoxy resin is low, showing good dimensional stability.

2.The chemical properties of epoxy resin are extremely stable, and are not affected by ordinary acids and bases, chemicals and industrial solvents.

3.Epoxy resin and a variety of materials have excellent adhesion, and itself has high strength mechanical properties, can withstand long-term environmental stress, to ensure a high degree of reliability.

Classification

           At present, the classification of epoxy resin has not been unified, generally according to the strength, heat resistance grade and characteristics of the classification, there are 16 main varieties of epoxy resin,

          Including general adhesive, structural adhesive, high temperature resistant adhesive, low temperature resistant adhesive, water and wet surface adhesive, conductive adhesive, optical adhesive, spot welding adhesive, epoxy resin film, foam adhesive, strain adhesive, soft material bonding adhesive, sealant, special adhesive, latent curing adhesive, civil construction adhesive.

Application

         Due to its excellent bonding performance, functionality, affordable and simple bonding process, it plays an indispensable role in the fields of aircraft, missiles, rockets, satellites, automobiles, ships, machinery, electronics and civil construction. There are many kinds of epoxy resin adhesives and they are widely used.

1.Flexible epoxy resin has the characteristics of high peeling strength, excellent impact resistance, thermal stress, fatigue, etc., and is widely used in aircraft honeycomb bonding and railway flooring. 

2.Toughened epoxy resins show strong impact resistance, fatigue resistance and environmental resistance, and are used in the adhesion of mobile phone towers, the assembly of weapons and equipment, and the manufacturing of sporting goods.

3.Single-component Epoxy adhesives are represented by 3M single-component epoxy adhesives with excellent environmental durability, resistance to extreme heat, cold, and humidity, and suitable for a wide range of solvents and other harsh conditions. Widely used in consumer electronics, military and aerospace and other fields.

4.Two-component epoxy adhesives offer hard and flexible options, similar to one-component epoxy adhesives, which are resistant to extreme conditions and meet the needs of customers in harsh environments.
