What are the functions of silicone oil in coatings Silicone oils generally refer to linear polysiloxane products that remain liquid at room temperature. Generally divided into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil, methyl silicone oil, is also known as ordinary silicone oil. Its organic groups are all methyl groups. Methyl silicone oil has good chemical stability, insulation, and good hydrophobicity. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain an initial polycondensation ring body. The ring body is cracked and rectified to obtain a low ring body. A mixture of different degrees of polymerization can be obtained by removing low boilers by distillation under reduced pressure.
The main applications of silicone oil and its derivatives are: release agent, shock absorption oil, dielectric oil, hydraulic oil, heat transfer oil, diffusion pump oil, defoamer, lubricant, hydrophobic agent, paint additive, polishing agent, cosmetics And daily necessities additives, surfactants, particle and fiber treatment agents, silicone grease, flocculants.
