Characteristics of epoxy resin

Application characteristics of epoxy resin softener
1. Various forms. Various resin, curing agent, and modifier systems can almost meet the requirements of various applications, ranging from extremely low viscosity to high melting point solids.
2. Convenient solidification. By using various curing agents, the epoxy resin system can almost cure within the temperature range of 0-180 ℃.
3. Strong adhesion. The inherent presence of polar hydroxyl and ether bonds in the molecular chain of epoxy resin makes it highly adhesive to various substances. The shrinkage of epoxy resin during curing is low, resulting in low internal stress, which also helps to improve adhesion strength.
4. Low contractility. The reaction between epoxy resin and the curing agent used is carried out through direct addition reaction or ring opening polymerization of epoxy groups in resin molecules, without the release of water or other volatile by-products. They exhibit very low shrinkage (less than 2%) during the curing process compared to unsaturated polyester resin and phenolic resin.
5. Mechanical properties. The cured epoxy resin system has excellent mechanical properties.
6. Electrical performance. The cured epoxy resin system is an excellent insulation material with high dielectric properties, surface leakage resistance, and arc resistance.
7. Chemical stability. Usually, cured epoxy resin systems have excellent alkali resistance, acid resistance, and solvent resistance. Like other properties of cured epoxy systems, chemical stability also depends on the selected resin and curing agent. Proper selection of epoxy resin and curing agent can give it special chemical stability properties.
8. Dimensional stability. The combination of many of the above properties gives the epoxy resin system outstanding dimensional stability and durability.
9. Resistant to mold. The cured epoxy resin system is resistant to most molds and can be used under harsh tropical conditions.
