Chemical structure: Epoxy resin is produced by the condensation reaction of epichlorohydrin and bisphenol A or polyphenol and other raw materials. Its molecular structure contains active epoxy groups (C-O-C), these groups can be cross-linked with a variety of curing agents.2.Performance characteristics:√High strength and hardness: epoxy resin can form a three-dimensional network structure with high cohesion after curing.√Good adhesion: excellent adhesive strength to metal, ceramics, glass, concrete, wood and many other materials.√Chemical resistance: can resist the erosion of a variety of chemical substances, including acid, alkali, salt, etc.√Electrical insulation: good electrical insulation properties, suitable for electronic and electrical industries √Temperature resistance: it can keep the performance unchanged in a certain temperature range, but the long-term high temperature may affect its performance.3.Application fields:√Coating: as anticorrosive coating, metal primer and insulating paint.√Adhesive: used in structural adhesive, electronic adhesive, etc.√Composite materials: used in the manufacture of FRP (fiber reinforced plastic) and other composite materials.√Electrical and electronics: used for encapsulation materials, insulation materials, etc.√Construction industry: used for epoxy floor paint, reinforcement materials, quick repair materials, etc.4. Curing process: it needs to react with curing agents (such as amines, anhydrides, phenolic resins, etc.) to form thermosetting plastics. The curing process can be either heat-promoted or at room temperature, depending on the type of curing agent and environmental conditions.5. Modification: The properties of epoxy resins can be modified to meet the needs of a particular application by the addition of various fillers, diluents, and other additives.2.What curing agents do we offer and how do they behave in epoxy resins?√.polyamides:produced by reacting dimerized and trimerized vegetable oleic acid or unsaturated fatty acids with polyamines. They have very good elasticity, adhesion and water resistance, good constructability, low toxicity, but lower heat resistance, usually the heat distortion temperature is only about 50 oC. It is suitable for construction in humid environment, but the curing speed is slow, may need to add accelerator, suitable for anticorrosive primer, floor paint and so on.√Aliphatic amines: this kind of curing agent has large dosage, mostly liquid, good miscibility with epoxy resin, can be cured at room temperature, but heat resistance is not high, usually need to be heated after curing to improve heat resistance.√Aromatic amine: the molecular structure contains benzene ring, alkaline, and epoxy resin reactivity is small, usually need to be heated curing, curing material has good heat resistance, drug resistance and mechanical properties, its modified curing agent can be applied to the floor primer.√Alicyclic amines: containing alicyclic structure of amine compounds, generally low-viscosity liquid, with a longer period of application and good mechanical strength, modified products can be cured at room temperature, suitable for epoxy flooring finishes and so on.√Polyether amines: These curing agents can enhance the elasticity, toughness, impact resistance and flexibility of the cured material, low viscosity, low color, low price, modified products can be applied to the floor paint materials in the paint and top coat, also suitable for the production of epoxy jewelry glue.√anhydride curing agent: By reacting with the hydroxyl group in the epoxy resin, it forms a stable cross-linking structure, which improves the thermo-mechanical properties and insulating properties of the material. Compared with amine curing agents, they usually need to be baked at higher temperatures to cure completely, and are usually used in the field of glass fiber reinforced polymer materials.
