Features Of 9-220-10 Hydrogen-containing Phenylmethyl Silicone Oil

  1. Contains reactive Si–H groups enabling efficient hydrosilylation with alkenes, alkynes, and functional silanes.

  2. Phenylmethyl backbone delivers superior thermal stability and resistance to UV degradation versus pure methyl silicone oils.

  3. Low volatility and high flash point ensure safe handling and processing in high-temperature industrial applications.

  4. Excellent compatibility with organic resins, silicones, and crosslinkers for formulation flexibility.

  5. Controlled molecular weight distribution ensures consistent reactivity and predictable cure kinetics.

Typical Applications Of 9-220-10 Hydrogen-containing Phenylmethyl Silicone Oil

  1. Hydrosilylation-based release coatings for high-performance industrial molds and paper liners.

  2. Crosslinking agent in heat-curable phenylmethyl silicone elastomers and gels.

  3. Functional additive in specialty antifoams for aggressive chemical process environments.

  4. Surface modifier for silica fillers and pigments in high-end coatings and adhesives.

  5. Intermediate for synthesizing branched or graft silicone polymers with tailored phenyl content.
