Epoxy resin (Epoxy Resin)

Epoxy resin (Epoxy Resin) belong to an epoxy oligomers, usually in liquid form, is a molecular structure containing two or two or more epoxy groups of organic compounds (Epoxide), the formation of the reaction heat, can interact with the hardener curing resin. With advances in technology continue to develop, a wide range of epoxy resin, which is most widely used by the polymerization of bisphenol A (DPP) and epichlorohydrin (ECH) reaction from the bisphenol A epoxy resin. Epoxy resin itself has no easy drying shortcomings, and therefore need the right amount of accelerator to assist the curing to achieve film hardening purposes.
 
Through different types of synthetic resin, epoxy resin and choose different hardener and filler added modifiers and become different properties of epoxy resin, its application on characteristics include:
 
Diversity:
Changes in a variety of different resins, hardeners, modifiers, can range from very low degree of adhesion to refractory solid to cope with the requirements of different forms.
Hardening easy:
By ing various hardeners, hardenable epoxy resin in the range of 0 to 180 degrees.
Adhesion of the strong:
Epoxy molecular chain due to the polar hydroxyl group and an ether bond exist, so a variety of materials having high adhesion, shrinkage during hardening of the epoxy resin is low, internal stress generated to help improve the degree of adhesion.
Low shrinkage:
An epoxy resin showing low shrinkage during hardening is due to the use of the reaction with the hardener is through direct addition reaction of epoxy groups in the molecule or resin polymerization carried out, there is no water or other volatile byproduct.
Dielectric strong:
Epoxy resin cured with a high degree of resistance to electrical properties, prevents surface leakage and insulation resistance.
Chemical resistance:
Cured epoxy resin usually has good salt tolerance, acid resistance and solvent resistance. As the face of the chemical stability of supplies, it must depend on the choice of resin and hardener, ie; suitably ed epoxy resin and hardener can make it with a special chemical stability.
Anti-fungal:
The vast majority of the cured epoxy resin can prevent mold, to avoid adverse effects of poor environmental conditions occurred.
Although the epoxy resin poor weather resistance and toughness, but by ing the appropriate method of epoxy resin and hardener, to a certain extent, it can be overcome and improve.
