XIAMETER® Silicones Simplified - from Dow Corning

XIAMETER® Brand Volatile Methylsiloxane Fluids

XIAMETER volatile methylsiloxane (VMS) fluids are volatile, nonreactive silicone fluids. They include both very-low-viscosity linear polydimethylsiloxanes (≤ 2 cSt) and cyclosiloxanes.

Features And Benefits

XIAMETER volatile methylsiloxane fluids give you the features and benefits of higher-viscosity polydimethylsiloxane fluids, but in a transient form.

Volatile polydimethylsiloxane fluids are slightly more persistent than cyclosiloxane fluids.

Typical Uses

  • General industrial cleaning formulations
  • Household care formulations, including furniture polishes, fabric cleaners and spot removers, carpet and upholstery cleaners, hard-surface cleaners
  • As carriers for many types of oils, lubricants and silicone polymers, allowing formulators to replace or dilute VOC-solvents to reduce the overall VOC impact
  • In the formulation of beauty and personal care products to improve spreading, rubout and lubricity
