2020-02-12The researchers first hydrolyzed the alkoxysilane into a prepolymer and then polycondensed it with a hydrogen-containing alkoxysilane to obtain a phenyl-containing hydrogen-based silicone resin. The p......
2020-02-12Researchers use hydrolysis and condensation to obtain phenyl silicone resin: phenyltrimethoxysilane, diphenyldimethoxysilane, vinyltrimethoxysilane are used as raw materials, and hydrochloric acid aqu......
2020-02-12At present, there are many patents on LED packaging materials, and phenyl packaging materials have the most research. A tetraphenylcyclotetrasiloxane and a vinyl double head are used as raw materials,......
2020-02-11According to its refractive index, it can be divided into two types: low refractive index (1.4) and high refractive index (1.5). The refractive index 1.4 is mainly methyl-type silicone materials, and ......
2020-02-11The organosilicon polymer has a Si—O bond as the main chain, and an organic group is connected to a silicon atom, and may have R3 SiO1 / 2 (M), R3 SiO2 / 2 (D), R3 SiO3 / 2 (T), R3 SiO2 ( Q) Combinati......
2020-02-11The researchers used alicyclic epoxy resins to react with diphenyldihydroxy and triphenylhydroxy groups to produce high refractive index (1.58), thermally stable, and UV-resistant silicone epoxy modif......
2020-02-11The chemical copolymerization method is to use reactive groups on the silicone polymer, such as hydroxyl, alkoxy, etc., to react with epoxy groups and other reactive groups on the epoxy resin to form ......
2020-02-11Epoxy resin has a high refractive index and light transmittance, and its mechanical properties and adhesive properties are quite good, so there are still certain products in the market that are being ......
2020-02-09LED (Light Emitting Diode) has the characteristics of energy saving, environmental protection, long life, low use voltage, short switching time, etc. It is widely used in many fields such as lighting,......
2020-02-09Organic-free silicone resin coatings have even better heat resistance: if pigments and fillers are added, these coatings can even withstand temperatures above 650 ° C for a short time. The heat resist......
2020-02-09Silicone-polyester-coated aluminum pans can withstand cooking temperatures of 250 ºC for longer periods of time, and even 300 ° C for short periods of time. In contrast, the heat resistance of trad......
2020-02-09The coated aluminum pan is the most basic kitchen utensil, which has the characteristics of light weight and low production cost. In addition, compared to expensive cast iron or stainless steel pans, ......
2020-02-09This high free volume characteristic can also be used for glass assembly and highway joint sealing. A special advantage of RTV silicone sealants is their ability to adapt to movements at the junctions......
2020-02-08PDMS has a high free volume, which results in a special atomic spacing of the silicone resin, so the polymer has a strong ability to penetrate gas and liquid. Quite unique medical applications resulti......
