Description

Cyclosiloxanes, Me Vinyl is a specialized organosilicon compound featuring a cyclic siloxane backbone with methyl and vinyl functional groups. This unique structure provides a versatile reactive site for cross-linking and polymerization, making it a crucial intermediate in advanced silicone manufacturing. It is essential for industries requiring high-performance elastomers, resins, and release coatings with enhanced thermal stability and mechanical properties.

Application

• Key monomer for the synthesis of vinyl-functional silicone fluids and gums.
• Cross-linking agent in the production of high-temperature vulcanized (HTV) and liquid silicone rubber (LSR).
• Intermediate for manufacturing silicone release coatings for labels and adhesive tapes.
• Building block for silicone resins used in protective coatings and electrical insulation.
• Modifier for improving the adhesion and compatibility of silicone materials with organic substrates.
• Used in the formulation of personal care products such as conditioners and hair treatments.

Quality Control

Our Cyclosiloxanes, Me Vinyl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to verify composition and identify impurities. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and organic solvents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
