What is Alkyd Resin -- 2023-04-13

Alkyd resin can be manufactured by melt polycondensation or solution polycondensation. The melting method involves heating glycerol, phthalic anhydride, fatty acids, or oil in an inert atmosphere to a temperature above 200 ° C, until the acid value meetsthe requirements, and then diluting with solvent. Solution polycondensation is a reaction in solvents such as xylene, which is both a solvent and an azeotropic liquid with water, which can increase the reaction rate. The reaction temperature is ...

Preparation of Addition Molded Silicone Resin -- 2023-04-12

The addition silicone resin refers to the silicone resin crosslinked and cured by catalytic hydrosilylation reaction of the base resin containing SiCH=C pressure and the polysiloxane crosslinker containing Si-H group. It is used as casting material and encapsulation material without bubbles and sand holes, has stable size, excellent heat shock resistance, is suitable for the impregnation and encapsulation of electrical equipment, and is also used as a protective coating for high-temperature adhe ...

lotion type silicone resin-Pure silicone resin lotion -- 2023-04-10

Pure organic silicone resin lotion, namely lotion type silicone resin (silicone resin lotion), has been widely used as building paint and adhesive, which has no pollution to the environment, no toxicity to human body, low production cost and good development momentum. The main preparation methods are as follows.(1) Generally, the silicone resin emulsification method is to make silicone resin prepolymer by co hydrolysis and condensation of mixed silica burning monomer, and then emulsified into si ...

Preparation of MQ Silicone Resin -- 2023-04-07

MQ resin is a type of organic silicon polymer compound with bright prospects and significant industrial application value. Firstly, it can be mass-produced from cheap water glass, rather than expensive raw materials such as organosilicon metal compounds and silicon; Secondly, unlike other organosilicon resins, it does not require strict control of the raw material ratio during the preparation process; Once again, it is easy to modify and has broad application prospects. The preparation methods o ...

Intermittent Synthesis of Methylphenyl Silicone Resin -- 2023-04-06

Among organic silicone resins, methyl silicone resin has the lowest carbon content and high heat resistance. The steric hindrance of methyl groups connected to silicon atoms is the smallest, and the resin has high cross-linking degree, high hardness, and low thermoplastic properties. It is a good waterproof and moisture-proof surface coating and adhesive. However, pure methyl silicone resin has poor compatibility with organic compounds, pigments, etc., low thermal elasticity, and limited applica ...

Phenyl Silicone Resin with Excellent Performance -- 2023-04-03

Silibase Silicone resin is mainly used to prepare silicone insulating paint, silicone coating, silicone adhesive and silicone plastic. High performance coatings such as high-grade building exterior wall coatings are the main market of silicone resin, and the main varieties are modified polyester and modified acrylic resin.Phenyl silicone resin is a silicone resin made by hydrolysis and polycondensation of PhSiX3 (X = Cl, OMe, OEt, etc.). Using the general hydrolysis polycondensation method, the ...

Hydrolysis and Condensation Process -- 2023-03-31

Hydrolysis condensation is the most important process in the synthesis of silicone resin. Generally, the hydrolysis condensation process involves evenly mixing methyl chlorosilane and methyl phenyl chlorosilane in a prescribed proportion with solvents such as toluene and xylene, and slowly adding them to excess water (or water and other solvents) under stirring for hydrolysis. During hydrolysis, maintain a certain temperature, and after hydrolysis, allow to stand until the silica alcohol and aci ...
