Octamethylcyclotetrasiloxane D4 is a colorless transparent or milky flammable liquid, a compound produced by hydrolysis synthesis after separation and rectification with dimethyldichlorosilane. It is an important intermediate in the silicon industry. It is mainly used for ring-opening polymerization with silicone oil, silicone rubber, and silicone resins with different degrees of polymerization. Products that are further processed into polymer products are widely used in various fields such as construction, electronics, textiles, automobiles, personal care products, food and mechanical processing, and also have a small number of direct applications.

Properties and Uses:
The
biggest advantage of methyl hydrogen silicone oil is its good waterproof
effect. It can be crosslinked into a film at a low temperature by a metal
salt catalyst, and a waterproof film can be formed on the surface of various
materials. It can be used as a waterproofing agent for various materials such
as fabric, glass, ceramic, paper, leather, metal, cement, marble. Especially
in the waterproof application of fabrics. Together with the methyl hydroxy
silicone oil emulsion, it is waterproof and maintains the original
breathability and softness of the fabric, and can improve the tear strength,
friction strength and antifouling properties of the fabric. In addition, it
can also be used as a paper release agent and cross-linking agent, as well as
a foaming agent for foamed silicone rubber.
Package, Storage and Handling:
Iron
drum, net weight 190kg/drum; Store in a cool, dry, well-ventilated area and
keep away from oxidant, acid and alkali. The storage area should be
equipped with the corresponding species and quantity of fire equipment and
leakage emergency equipment. Handling according to hazardous substances. Be
careful when loading and unloading to avoid damages of the package.
