  • Wearable

Product Details

Epoxy resins generally refer to organic polymer compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain, and the epoxy group can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure.


characteristic

Various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications, ranging from very low viscosity to high melting point solids. Various curing agents are used for curing, and the epoxy resin system can be cured at a temperature range of 180℃.

Strong adhesion

The inherent polar hydroxyl groups and ether bonds in the molecular chain of epoxy resins make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength.

Strong contraction

The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are emitted. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.

Mechanical properties

The cured epoxy resin system has excellent mechanical properties.

Electrical properties

The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance.

Chemical stability

Generally, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of cured epoxy systems, chemical stability also depends on the resin and curing agent selected. Appropriate selection of epoxy resin and curing agent can make it have special chemical stability.

Dimensional stability

The combination of many of the above properties gives the epoxy resin system outstanding dimensional stability and durability.

Mold resistant

The cured epoxy resin system is resistant to most molds and can be used in harsh tropical conditions.
