Features Of 1-201-1000 Dimethyl Silicone Oil

  1. Exceptionally low volatility and high thermal stability up to 200 °C in continuous service.

  2. Outstanding water repellency and surface slip without migration or staining.

  3. Chemically inert toward acids, bases, and most organic solvents under standard conditions.

  4. Low surface tension (≈20–22 mN/m at 25 °C) enabling uniform film formation and substrate wetting.

  5. Non-toxic, non-irritating, and compliant with FDA 21 CFR 175.300 for incidental food contact applications.

Typical Applications Of 1-201-1000 Dimethyl Silicone Oil

  1. Release agent for rubber and plastic molding, including silicone rubber and thermoplastic elastomers.

  2. Base fluid in personal care formulations such as hair conditioners, skin creams, and antiperspirants.

  3. Lubricant additive in precision instruments, optical assemblies, and micro-electromechanical systems (MEMS).

  4. Defoaming and foam control agent in industrial coatings, adhesives, and textile finishing baths.

  5. Surface modifier for enhancing hydrophobicity and abrasion resistance in architectural sealants and construction additives.
