Application

Hydrosilylation Catalysts
Catalyst for:
  • Reduction of carboxamides with hydrosilanes
  • Hydrosilylation of siloxanes
  • Dehydrocoupling polycondensation reactions
  • Hydrolysis of trichlorosilanes

Storage and Stability

1. Hygroscopic material, always handle in a glove bag or a glove box filled with dry inert gas
2. Recommended for one time use to prevent water absorption and degradation. If necessary, once opened, repack and seal under dry inert gas.
3. Store with care. Prevent from light. Always store in well-sealed containers in a dry inert atmosphere. Recommended to store containers in a secondary desiccator with desiccant in a dry inert atmosphere.
