The molecular structure of the epoxy resin is a molecular chain containing reactive epoxy groups of its characteristics, the epoxy groups may be located at the end of the molecular chain, or a cyclic intermediate structure. Since the molecular structure containing reactive epoxy groups, so that they can take place crosslinking reaction with various types of curing agents to form insoluble, infusible polymer having a three-to mesh structure. ⑴ Application Features ① forms. Various resins, curing agents, modifiers system can be adapted to the requirements of almost all kinds of applications made to the form, which can range from very low viscosity to high melting solids. ② cured easily. Use a variety of different curing agents, epoxy resin systems can be cured at a temperature almost 0 ~ 180 ℃ range. ③ strong adhesion. Inherent in the presence of epoxy resin molecular chains and a polar hydroxyl ether bond to a variety of substances with high adhesion. Epoxy curing low shrinkage, internal stress generated, which also helps to improve the adhesion strength. ④ low shrinkage. The reaction of the epoxy resin and the curing agent is used by direct addition reaction epoxy resin molecule or ring-opening polymerization reaction carried out, without water or other volatile byproducts released. They are unsaturated polyester resins, phenolic resins compared to exhibit very low shrinkage (less than 2%) during the curing process. ⑤ mechanical properties. The cured epoxy resin system with excellent mechanical properties. ⑥ electrical properties. The cured epoxy resin system is a high dielectric properties, resistance to surface leakage resistance, arc excellent insulating material. ⑦ chemical stability. Typically, the cured epoxy resin system with excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy systems, like the chemical stability also depends on the choice of resin and hardener. Appropriate selection of the epoxy resin and curing agent along with special chemical stability. ⑧ dimensional stability. Many properties of a combination of all of the epoxy resin system has outstanding dimensional stability and durability. ⑨ mildew resistant. Cured epoxy resin system resistant to most fungi, can be used in harsh tropical conditions. ① high performance characteristics and mechanical properties of the cured epoxy resin ⑵. Epoxy resin has a strong cohesive force, dense molecular structure, so its mechanical properties than a phenolic resin and an unsaturated polyester and other general type thermosetting resin. ② Excellent adhesion properties. Epoxy curing system activity greatly epoxy group, hydroxyl group and an ether bond, an amine bond, an ester bond and polar group in the cured epoxy imparting high adhesive strength. Plus it has the mechanical properties of high cohesive strength, so it is particularly strong adhesive properties, can be used as structural adhesive. ③ curing shrinkage rate is small. Typically at 1% to 2%. Thermosetting resin shrinkage is the smallest species of curing (phenolic resin 8% to 10%; unsaturated polyester resin is 4% to 6%; silicone resin is 4% to 8%). Linear expansion coefficient is small, typically 6 × 10-5 / ℃. So its products dimensional stability, low internal stress, easy to crack. ④ technology is good. When the epoxy resin curing substantially no low molecular weight volatiles, it is possible to contact the low pressure molding or pressure molding. Great flexibility in formulation design, can be designed for a variety of process requirements of the recipe. ⑤ good electrical properties. Is one of the thermosetting resin dielectric properties of the best varieties. ⑥ good stability. Epoxy substandard alkali, salt and other impurities perishable. As long as proper storage (sealed, not wet, not when the temperature), the storage period of 1 year. After extended if the inspection can still be used. Cured epoxy has excellent chemical stability. Its variety of media corrosion resistance and alkali, acid, salt and other than unsaturated polyester resins, phenolic resins and other thermosetting resins. ⑦ heat resistance of cured epoxy is generally 80 ~ 100 ℃. Epoxy heat up to 200 ℃ or more varieties. ⑧ thermosetting resin, overall performance and the cured epoxy most
