Silicone Fluid Rx 200
100 percent active, 100 cSt, polydimethylsiloxane polymer. INCI Name: Dimethicone.
Silicone Fluid RX 200 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers in a wide range of average kinematic viscosities. The viscosities generally used in formulating polishes are between 100 and 30,000 cSt. 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. 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.
- Active ingredient in a variety of automotive, furniture, metal and specialty polishes in paste, emulsion and solvent-based polishes and aerosols.
- Various applications including cosmetic ingredient, elastomer and plastics lubricant, electrical insulating fluid, foam preventive or breaker, mechanical fluid, mold release agent, surface active agent, and solvent-based finishing and fat liquoring of leather.
Silicone Fluid Rx 200 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 water with standard emulsifiers and normal emulsification techniques. Silicone Fluid Rx 200 cSt is insoluble in water and many organic products. Additive quantities as small as 0.1% may suffice where Silicone Fluid Rx 200 Silicone Fluid, 50–1,000 cSt is to be used as a surface agent or for de-soaping creams and lotions. However, 1–10% is needed for applications such as hand creams and lotions to form a more uniform film and effective barrier.
