Guangdong epoxy resin with silica powder prices where good

First, the epoxy resin with silica powder Overview: epoxy silane and other materials with silica powder particles of silica powder surface modification, so that the surface layer of thin and solid silane coupling agent film, which its fortune The original surface properties, it has a water-repellent, improved epoxy resin and silicone resin materials and filling systems, mechanical, electrical and chemical properties. Second, our product specification sheet: epoxy resin with silica powder 400 mesh size 600 mesh 800 mesh mesh 1250 1000 1500 4000 2000 mesh mesh mesh mesh 8000 6000 10,000 head three head, epoxy and silicon powder Relations: Silica epoxy resins is ideal for packing, can improve the performance of some products, and to improve the cooling conditions when the resin is cured, the filler material may be reduced by the amount of the epoxy resin, to reduce costs. Due to different uses can choose different fillers, the amount depending on the application. Common portion of the filler described as follows: Name Role filler quartz powder, ceramic powder, iron, cement, asbestos increase the hardness of silicon carbide powder, quartz powder, powder reduce shrinkage graphite, talc, quartz powder to improve abrasion resistance and lubricity mica , porcelain powder, quartz powder increased insulation performance four epoxy with silica powder Features: 1, technology is good. When the epoxy curing substantially no low molecular weight volatiles, it can be low-pressure molding or a contact pressure molding. Can meet a variety of manufacturing and curing agent solvent-free, high solids, powder coatings and water-based paints and other environmentally friendly paint. The heat resistance of the cured epoxy is generally 80 ~ 100 ℃. Epoxy heat up to 200 ℃ or more varieties. 2, good stability, good chemical resistance. No alkali, salt and other impurities epoxy perishable. As long as proper storage (seals, not damp, not when the temperature), the storage period of one 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 an unsaturated polyester resin, phenol resin thermoset resins. Therefore widely used as anti-corrosion epoxy primer, epoxy resin cured because of a three-dimensional network structure, and the ability of dipping oils, etc., widely used in tanks, tankers, flying chicken whole tank inside wall linings. 3, curing shrinkage is small, typically 1% to 2%. Thermosetting resin shrinkage is the smallest one curable species (phenol 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 / ℃. Therefore, little change in volume after curing. 4, high mechanical properties and excellent electrical insulating properties. Epoxy resin has a strong cohesive force, the molecular structure of dense, so its mechanical properties than phenolic resins and unsaturated polyester and other general type thermosetting resin, an epoxy resin is one of the best varieties of thermosetting resin dielectric properties. 5, strong adhesion. Epoxy curing system containing the active greatly epoxy, hydroxyl and ether bond, amine bond, an ester bond and other polar groups, giving the cured epoxy to metal, ceramics, glass, concrete, wood and other polar groups material with excellent adhesion.
