Targeted Industrial Applications

Engineered strictly for high-performance chemical bonding and modification.

LSR & RTV-2k Base Polymer: Mainly used as the base rubber for addition-type liquid silicone rubber. It acts simultaneously as a reinforcing agent, hardening agent, and structured control agent within the silicone rubber industry. Can be used as a blend polymer to create desired hardness.

Chemical Synthesis & Modification: Taking advantage of its high vinyl reaction activity, it is used to produce perfusion silicone rubber and to synthesize silicone-modified acrylic resin emulsions. It also serves as a major intermediate for other organic silicone materials.

Industrial Finishing Agents: Applied broadly as a waterproof agent, softening agent, and antisticking agent across the fabric, paper, and leather manufacturing industries.

Packaging & Shelf Life Constraints

Standard Packaging & Capacity: Packaged strictly in net weight 190 kg steel drums or 950 kg IBC drums. A standard 20’ GP FCL can full-load either 80 steel drums (15,200.0 kg) or 18 IBC drums (17,100.0 kg).

Storage Parameters: The fluid possesses a shelf life of 36 months when stored in the original unopened packaging at ambient temperatures. The product does not freeze, ensuring there are no extreme low-temperature restrictions on storage.

System Loop: Engineer Q&A;

What is the exact crosslinking mechanism for formulating LSR with the 206 series?

The terminal vinyl groups of the polydimethylsiloxane fluid participate in an addition-curing vulcanization reaction. This requires blending with silicon-hydride (Si-H) crosslinkers and must be catalyzed by a platinum catalyst to achieve the final elastomer network.

How does the vinyl content scale with viscosity across the product grades?

The relationship is strictly inverse. Low-viscosity grades like MESIL® 206-20 (20 cSt) feature a high vinyl content of 2.80~3.47 wt%, providing high crosslink density. Conversely, high-viscosity grades like MESIL® 206-20000 (20,000 cSt) feature a low vinyl content of 0.09~0.13 wt%, suitable for softer, high-elongation rubber bases.
