It is feasible to use ordinary dimethyl silicone oil in water-soluble DEET systems, but it is necessary to disperse it in the aqueous phase through emulsification technology and select the appropriate viscosity to balance stability, skin feel and mosquito-repellent effect. The following is a detailed analysis and suggestions:

Using 5 cSt (centistokes) dimethyl silicone oil as a surface smoothing agent for enameled wires is not suitable. The following analysis is conducted from three dimensions: technical principles, industry practices, and practical applications.

In the application of motor carbon brushes, dimethyl silicone oil (polydimethylsiloxane, PDMS) is the most commonly used type of silicone oil, and its viscosity is usually 100 mm²/s (centistokes, cSt). The specific analysis is as follows:

When selecting dimethyl silicone oil as a defoamer in antifreeze, a comprehensive assessment is required based on the system’s characteristics, the impact of viscosity, and practical application needs. Below is a key analysis and recommended solution:

The selection of silicone oil type and viscosity for thermal grease needs to be comprehensively determined based on application scenarios, heat dissipation requirements, and other factors. The specific analysis is as follows:

When using dimethyl silicone oil as a defoamer in tattoo ink, it is recommended to choose products with a viscosity range of 50~200 centistokes (cSt). The following is a detailed analysis and suggestions:

The compatibility between 500# White Mineral Oil and Dimethyl Silicone Oil is excellent—they form a "highly compatible combination" commonly used in industry, with better compatibility than that between 500# White Mineral Oil and Amino Silicone Oil (since Dimethyl Silicone Oil contains no polar groups, making it more chemically compatible with White Mineral Oil). A detailed analysis from the perspective of chemical nature, compatibility performance, and practical application verification is as follows:

The UV resistance, water resistance, and acid-alkali resistance of Amino-Terminated Polydimethylsiloxane (amino silicone oil) are closely related to its molecular structure, amine value (amino group content), and modification process. The following is a comprehensive analysis based on existing research and application practices:

It should first be clarified that ordinary dimethyl silicone oil (composed only of -Si(CH₃)₂-O- main chains, without reactive functional groups such as hydroxyl groups or vinyl groups) cannot be cured through chemical means using crosslinking agents and curing agents.
