Features Of 9-210-20K Vinylphenylmethyl Silicone Oil

  1. High thermal stability with continuous service temperature up to 200 °C.

  2. Excellent compatibility with organic resins, vinyl polymers, and phenolic systems.

  3. Low volatility and minimal outgassing under vacuum or elevated-temperature conditions.

  4. Reactive vinyl groups enable covalent bonding in crosslinking formulations.

  5. Phenyl substitution enhances UV resistance and reduces refractive index variation.

Typical Applications Of 9-210-20K Vinylphenylmethyl Silicone Oil

  1. Release agent for high-temperature composite molding (e.g., CFRP, GFRP).

  2. Functional additive in silicone-modified acrylic and epoxy coatings.

  3. Base fluid in specialty heat-transfer fluids for semiconductor processing equipment.

  4. Viscosity modifier and surface conditioner in LED encapsulation gels.
