The organic silicone resin and organic resin are connected by chemical method to form a whole, which will be beneficial to the comprehensive performance of the two materials. Generally speaking, only chemical reaction modification with organic resin can the silicone resin get good results. The chemical modification mainly adopts the methods of CO condensation and copolymerization and co addition reaction, usually at the end of siloxane chain or at the end of siloxane chain The side group is used to combine with organic polymer to form block, graft or interpenetrating network copolymer, so that silicone resin can obtain new properties and applications.
Organosilicon resin
What should be noted for silicone resin
1. when using silicone resin, it should avoid contacting with acid and alkali, organic salt and amine, otherwise, curing and gelatinization will be accelerated, which will affect the performance of the product.
2. the diluent used shall not contain water, sulfide and other impurities, otherwise it will affect the adhesion dry and other properties of the paint film.
3. a large number of flammable and explosive gases such as organic solvents will be emitted during the process of organosilicon resin processing. Attention should be paid to strengthening ventilation on the operation site and fire prevention, and the operators who cut off the fire source should pay attention to labor protection.
