Silicone oil is manufactured to yield essentially linear polymers in a wide range of average kinematic viscosities.
It is highly soluble in organic solvents such as aliphatic and aromatic hydrocarbons,and the halocarbon propellants used in aerosols. The fluid is easily emulsified in waterwith standard emulsifiers and normal emulsification techniques. But it is insoluble in water and many organic products.The viscosities generally used in formulating polishes are between 100 and 30,000cst. To obtain optimum results, in terms of ease of application and depth of gloss, it is preferable to use a blend of a low-viscosity fluid and a high-viscosity fluid.(e.g. 3 parts 100cst and 1 part 12,500cst). The low-viscosity silicone fluid acts as a lubricant to make polish application and rubout easier, whereas the high viscosity silicone fluid produces a greater depth of gloss.Since these polymers are inherently water repellent, they will cause water to bead up on a treated surface rather than penetrate the polish film.
