Features Of 1-201-100 Dimethyl Silicone Oil

  1. High thermal stability with consistent viscosity across a wide temperature range (−40 °C to +200 °C).

  2. Excellent water repellency and low surface tension for superior spreading and wetting performance.

  3. Chemically inert and non-reactive with most acids, bases, and solvents under standard processing conditions.

  4. Odorless, colorless, and non-volatile — meets strict requirements for cosmetic and pharmaceutical-grade formulations.

  5. Low volatility and negligible vapor pressure, ensuring long-term stability in sealed and open systems.

Typical Applications Of 1-201-100 Dimethyl Silicone Oil

  1. Personal care formulations including hair conditioners, skin moisturizers, and makeup primers.

  2. Industrial lubricants for precision instruments, plastic gears, and rubber-to-metal interfaces.

  3. Release agents in silicone mold making, polyurethane foaming, and composite manufacturing.

  4. Dielectric fluid in high-voltage transformers and electronic potting compounds.

  5. Defoaming and antifoaming carrier in water-based paints, adhesives, and industrial cleaning agents.
