Applications
The Silicon Hydride groups of GP-535 provide a reactive site, allowing reaction with a variety of materials containing vinyl groups or with hydroxyl functional polysiloxanes in combination with heat or metal catalysts. Other applications include:
- Room Temperature Curing Silicone rubber Component
- Cross-linking Agent for Vinyl Cured Silicones
- Water Proofing Agent for Textiles, Paper and Leather
- End-Blocker for Silicone Fluid Synthesis
Processing and Safety Guidelines
GP-535 reacts with water, alcohols or other reactive hydrogen compounds, to liberate hydrogen gas. Since the hydrogen is Flammable and also will cause pressure build-up in closed containers, use all proper precautions when handling these products.
Alkaline materials will cause a rapid release of hydrogen, when in contact with GP-535, and must be avoided.
GP-535 is a flammable liquid and may cause skin irritation. Consult Safety Data Sheet for additional safety information.
Packaging/Handling/Storage
GP-535 (1,1,3,3 Tetramethyldisiloxane) is supplied in 5-gallon (11 kg.) pails and 55-gallon (150 kg.) drums.
