1-200-15 Terminally Hydrogen-terminated Silicone Oil

Dow Corning® 200 Fluid Series 1-200-15 is a low-viscosity, hydrogen-terminated linear polydimethylsiloxane with reactive Si–H end groups. It serves as a key precursor for hydrosilylation-cured silicones, offering excellent thermal stability, low volatility, and precise molecular weight control (≈1,500 g/mol). Widely used in specialty coatings, release agents, and silicone elastomer synthesis.

Features Of 1-200-15 Terminally Hydrogen-terminated Silicone Oil

  1. Highly reactive Si–H end groups enable efficient hydrosilylation with alkenes, alkynes, and functional silanes.

  2. Low viscosity (15–25 cSt at 25 °C) ensures excellent processability and uniform dispersion in formulations.

  3. Excellent thermal stability up to 200 °C under inert atmosphere, supporting high-temperature curing processes.

  4. Hydrogen termination provides superior compatibility with silicone elastomers, resins, and crosslinkers.

  5. Low volatility and negligible extractables meet stringent requirements for medical device and electronics encapsulation.

Typical Applications Of 1-200-15 Terminally Hydrogen-terminated Silicone Oil

  1. Crosslinking agent in platinum-catalyzed addition-cure liquid silicone rubber (LSR) systems.

  2. Functional modifier for silicone pressure-sensitive adhesives (PSAs) to enhance cohesion and heat resistance.

  3. Surface treatment agent for silica fillers and inorganic pigments in high-performance composites.

  4. Intermediate in synthesis of silicone surfactants, dendrimers, and hybrid organic–inorganic polymers.

  5. Release additive in mold coatings for precision casting and optical lens manufacturing.
