- Typical Properties
- Note
- 1 The melt point temperature is a typical value and may vary somewhat due to molecular distribution. 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.

Technical Details & Test Data
- Technical Details on Powder Applications
Silicone fluids spread easily on the skin and reduce tackiness.
This volatile silicone carrier provides a dry and smooth feel while reducing greasiness and tackiness. It can be selected or blended depending on the volatility needed for the application.

Safety & Health
- Handling Precautions
- XIAMETER™ PMX-200 Silicone Fluid may cause temporary eye discomfort.
- Use caution when handling volatile fluids at temperatures within 10°C of the quoted flash point.
- XIAMETER™ PMX-200 Silicone Fluid with viscosities below 5 cSt are flammable. Keep away from heat, sparks, open flames and other sources of ignition. Keep container tightly closed.
- At elevated temperatures, XIAMETER™ PMX-200 Silicone Fluids are sensitive to contamination by strong acids, bases, some metallic compounds and oxidizing agents. These contaminants may cause an accelerated rate of volatile byproduct formation. Oxidizing agents can also cause an increase in fluid viscosity. When these conditions may exist, it is recommended that the flash point of the fluids be checked periodically to monitor operational safety. Also, ignitable conditions may exist if the fluid is giving off smoke.
Storage & Handling
- Usable Life and Storage
Product should be stored at or below 25°C (77°F) in original, unopened containers.
