With the rapid development of modern industry and production industries, people more and more high to the requirement of heat resistance coating, need not only at a higher temperature and more stringent corrosion and climate harsh environments such as homework, but also with impact resistant, high hardness and resistance to weathering performance, such as ordinary silicone has been difficult to protect the base material, the demand for high temperature resistant organic coating is more and more urgent.
Among them, the development of high temperature resistant silicone coating is more common. As a film forming material of coatings, silicone resin is a key factor in the performance of coatings. Its unique thermal stability and oxidation stability make silicone resin widely used in coatings. Organic silicon resin synthesis method are many, including organochlorine silane as raw material, adopting Chemicalbook hydrolytic condensation method the synthesis methods of methyl phenyl silicone attention, the method of raw materials produced by the direct method, reactants, large output, low cost, but this method in the process of the reaction to generate large amounts of hydrogen chloride gas, hydrogen chloride gas heat emission when soluble in water, Hydrochloric acid and heat accelerated the spontaneous condensation of silanol, the intermediate of hydrolysis reaction, making the reaction system easy to gelation. Application of methyl phenyl silicone resin because of the introduction of phenyl silicone oxygen chain, so that its mechanical properties, thermal elasticity, bonding, gloss and compatibility with organic, inorganic filler and other aspects of methyl silicone resin is obviously superior, can be used as high temperature insulating paint, high temperature adhesive.
The following is an introduction to IOTA's phenyl silicone resins:
