Features Of 1-000-20 High-Hydrogen Silicone Oil

  1. High active hydrogen content enables efficient hydrosilylation reactions with alkenes and alkynes.

  2. Low viscosity (20–25 cSt at 25°C) ensures excellent processability and uniform dispersion in formulations.

  3. Thermally stable up to 200°C, supporting high-temperature curing processes without premature decomposition.

  4. Consistent molecular weight distribution ensures reproducible reactivity and crosslink density.

  5. Compatible with platinum-based catalysts and widely used silicone polymers for seamless integration.

Typical Applications Of 1-000-20 High-Hydrogen Silicone Oil

  1. Hydrosilylation-curable liquid silicone rubber (LSR) systems for medical and automotive components.

  2. Crosslinking agent in heat-cured silicone gels for electronics encapsulation and thermal interface materials.

  3. Functional additive in silicone release coatings for paper, film, and composite manufacturing.

  4. Reactive diluent and chain extender in specialty silicone resins for high-performance coatings.

  5. Hydrogen donor in silicone-based adhesives and pressure-sensitive adhesive (PSA) formulations.
