- 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.

- Typical Properties
- Note
- 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.
- 2 Due to different rates of cooling, this test method may yield pour points lower than the temperature at which these fluids would melt.
