Basic Info of Dimethyldimethoxysilane

What is Dimethyldimethoxysilane?

Dimethyldimethoxysilane is a monomer alkyl alkoxysilane. It hydrolyzes in contact with water, releases methanol, forms highly reactive silanol, and further condenses to form oligomeric and polysiloxane.

Dimethyldimethoxysilane is mainly used in these aspects:

  • In the synthesis of chemical intermediates.
  • As an additive in the production of silicone resin.
  • In the hydrophobicization of the surface, such as glass, pigment, etc.

Dimethyldimethoxysilane Uses

  1. Dimethyldimethoxysilane, sometimes abbreviated as dmdeos or dmdes, is a silicone compound. Dmdeos is a precursor for the production of silicone polymer polydimethylsiloxane (PDMS).
  2. Dimethyldimethoxysilane is used as silylating agent for diols. It is used as a monomer (“structural unit”) in the production of silicone polymer or silicone resin and as an intermediate (starting material) in the production of other silicone substances. It is also used for non-metallic surface treatment to enhance the adhesion of the surface. Laboratory chemicals used in sealants, silicone polymer preparations (for the production of elastomers), mold manufacturing, semiconductor manufacturing and R & D activities.
  3. Dimethyldimethoxysilane (DMDMS) can be used to:
    • Various macroporous silica aerogels were synthesized.
    • Hollow silica nanoparticles loaded with phthalocyanine were prepared for near-infrared photodynamic and photothermal combined therapy.
    • Synthesis of dielectric silicone elastomer with high dielectric constant.
  4. Dmdeos is an intermediate silane, which can be used to block hydroxyl and amino groups in organic synthesis reactions. This silylation step allows a subsequent reaction that will be adversely affected by the active hydrogen present in the hydroxyl or amine group. After the reaction step, the hydroxyl or amine terminated by dmdeos can be recovered by hydrolysis procedure. Dmdeos is also used to prepare hydrophobic and demoulding materials and enhance the fluidity of powder.
  5.  As a structural control agent, chain extender and filler treatment agent, it is widely used in the treatment of organic silica gel and silica. This product is used as a structure control agent and chain extender to improve the mechanical processing performance and prolong the storage time of the rubber mixture. It can be used instead of hydroxyl silicone oil. It is widely used in the treatment of organic silica gel and white carbon black

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
