Import Divinyl Tetramethyl Disiloxane — Buy in Bulk from Supplier in China

Divinyl tetramethyl disiloxane is a clear, colorless liquid with the molecular formula C8H18OSi2, used primarily as a vinyl-blocking agent in silicone formulations. The product is supplied with a purity of at least 99.0% and a vinyl content of approximately 27.5%, as confirmed by the supplier's technical data. Its refractive index ranges from 1.4118 to 1.4123, and its density is 0.818 g/ml at 20°C, consistent with industry benchmarks for this compound.

This compound is typically employed as an intermediate in platinum-catalyzed addition curing systems, particularly in liquid silicone rubber and silicone gel production. It enhances crosslinking efficiency and is compatible with common solvents such as toluene and isopropanol. The thermal stability of this material allows it to remain inert under processing temperatures up to 180°C, making it suitable for high-temperature curing applications in industrial molding and coatings.

Buyers in the personal care, adhesives, and industrial coatings sectors commonly source this material for its predictable reactivity and low volatility. Packaging is typically in 20kg plastic pails or 160kg metal drums, though custom packaging may be available. Trade terms are flexible, with T/T and L/C accepted, but MOQ and lead time are not specified and must be confirmed directly with the supplier. Storage should be in sealed containers under inert atmosphere to prevent moisture absorption.
