- Product Highlights
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 (e.g. 3 parts XIAMETER™ PMX-200 Silicone Fluid 100 cSt and 1 part XIAMETER™ PMX-200 Silicone Fluid 12,500 cSt). 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.
- Product Highlights for Automotive Application
- High-viscosity fluids provide excellent depth of gloss and improvements in durability and water resistance.
- Useful in solvent-based formulations.
- Blend of intermediate- and high-viscosity fluids recommended to achieve a good balance in gloss, application ease and rub-out.

- Recommended Applications
- 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.
- Usage
XIAMETER PMX-200 Silicone Fluid, 500 cSt 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. XIAMETER PMX-200 Silicone Fluid, 500 cSt is insoluble in water and many organic products. Additive quantities as small as 0.1% may suffice where XIAMETER PMX-200 Silicone Fluid, 500 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.

- Note
- 1 The melt point temperature is a typical value and may vary somewhat due to molecular distribution (especially 50 cSt). If the melting point is critical to your application, then several lots should be thoroughly evaluated.
- 2 Due to different rates of cooling, this test method may yield pour points lower than the temperature at which these fluids would melt.
