Premier Repak Inc. PRSF 350-1,000 CST 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 (e.g. 3 parts PremierRepak Inc. PRSF 100 CST and 1 part PremierRepak Inc. PRSF 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.
