Features Of Wacker CATALYST OL Platinum Catalyst

  1. Highly active hydrosilylation catalyst based on platinum(0) complex for rapid and selective Si–H addition to alkenes.

  2. Excellent thermal stability up to 150 °C, enabling robust performance in high-temperature curing processes.

  3. Low volatility and minimal odor—designed for safe handling and reduced VOC emissions in industrial settings.

  4. Compatible with a broad range of silicone polymers, including vinyl-functional PDMS, MQ resins, and functional silanes.

  5. Consistent batch-to-batch reproducibility, certified under WACKER’s stringent quality control system (ISO 9001).

Typical Applications Of Wacker CATALYST OL Platinum Catalyst

  1. Room-temperature and heat-cured liquid silicone rubber (LSR) for medical devices and automotive seals.

  2. Platinum-cure silicone gels and foams used in electronics encapsulation and cushioning materials.

  3. Adhesives and coatings requiring high clarity, low extractables, and long pot life before cure.

  4. Functionalized silicone intermediates for personal care formulations (e.g., volatile-free emollients).

  5. 3D printing resins based on silicone chemistry requiring precise, inhibition-free crosslinking.
