What are the main ingredients of silicone thinner?
The main components of silicone diluent vary depending on the type and purpose. The following are the main components of some common silicone diluents:
Organic solvents:
Toluene, xylene: They are common aromatic organic solvents that have a certain ability to dissolve and dilute silica gel. Toluene is a colorless, clear liquid with a benzene-like odor; xylene is the product of two hydrogens on the benzene ring being replaced by methyl groups. There are three isomers, ortho, meta, and para. In industry, xylene refers to a mixture of these three isomers. In some silica gel dilutions, they can effectively reduce the viscosity of silica gel, making it easier to construct and operate, but such organic solvents have certain toxicity and volatility, so safety and ventilation should be paid attention to when using them.
Cyclohexane: It is an organic compound, a colorless liquid with a pungent odor. It is insoluble in water and easily soluble in organic solvents such as ethanol and ether. It can be used as a diluent for silica gel. Its molecular structure is relatively stable. It can maintain good chemical stability during the dilution of silica gel, which helps to evenly disperse silica gel, but it also has certain volatility.
Silicone oil:
Methyl silicone oil: This is the most commonly used type of silicone oil, with the chemical name polydimethylsiloxane. It is a colorless and transparent oily liquid with good chemical stability, electrical insulation and high and low temperature resistance. In the dilution of silicone, methyl silicone oil can not only reduce the viscosity of silicone, but also improve the flexibility and demolding properties of silicone to a certain extent. In addition, its volatility is low, and the harm to the environment and human body is relatively small. It is a relatively safe silicone dilution component.
Phenyl silicone oil: A type of polysiloxane with a silicon-oxygen bond as the main chain and a phenyl group introduced on the silicon atom. In addition to the characteristics of general silicone oil, it also has higher temperature resistance and radiation resistance. When used for silicone dilution, it can give silicone better high temperature resistance and radiation resistance, and is suitable for the dilution of some special silicone products with high environmental requirements.
Hydrogen-containing silicone oil: Polysiloxane containing silicon-hydrogen bonds (Si-H) in the molecular structure. Under certain conditions, the silicon-hydrogen bonds in hydrogen-containing silicone oil can react with other substances containing active groups (such as double bonds) to play a role in crosslinking or modification. During the dilution of silicone, it can not only reduce the viscosity of silicone, but also participate in the vulcanization reaction of silicone, affecting the degree of cross-linking and final performance of silicone, such as improving the hardness and strength of silicone.
