XIAMETER(TM) PMX-200 Silicone Fluid 12,500 cSt

XIAMETER(TM) PMX-200 Silicone Fluid 12,500 cSt is a high-viscosity polydimethylsiloxane polymer manufactured to yield essentially linear polymers in a wide range of viscosities. The viscosities generally used in formulating polishes are in the range of 100 to 30,000 cSt. It is preferable to use a blend of a low-viscosity fluid and a high-viscosity fluid (e.g. 3 parts XIAMETER(TM) PMX- 200 Silicone Fluid 100 cSt and 1 part XIAMETER(TM) PMX-200 Silicone Fluid 12,500 cSt) to obtain optimum results in terms of ease of application and depth of gloss. 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.

Use Procedure

XIAMETER PMX-200 Silicone Fluid is insoluble in water and many organic products. It is highly soluble in organic solvents such as aliphatic and aro-matic hydrocarbons, and the halo-carbon propellants used in aerosols. The fluid is easily emulsified in water with standard emulsifiers and normal emulsification techniques.

As An Antifoam

  • The starting level of active material in nonaqueous foam control is 10 ppm. In many cases, the optimal usage level may be 1~100ppm. XIAMETER PMX-200 Silicone Fluid is typically prediluted in a hydro-carbon solvent, such as white spirits, toluene, xylene, diesel, naphtha or another low molecular weight petroleum fraction, and added continuously by metering pump.

As A Conditioning Additive

  • Additive quantities as low as 0.1% may suffice where XIAMETER PMX-200 Silicone Fluid is to be used as a surface treatment 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.

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