Vinylmethyldimethoxysilane CAS NO: 16753-62-1 QM-Y2171

Dimethoxymethylvinylsilane is an important monomer for synthesizing high-performance organosilicon materials. In the production of silicone rubber, it is often used to prepare vinyl silicone oil or as a capping agent. These vinyl-containing polysiloxanes, as base polymers, undergo vulcanization reactions with crosslinking agents such as hydrogen-containing silicone oils under platinum catalysis to produce silicone rubber with excellent high-temperature resistance, aging resistance, and weather resistance, widely used in sealing, vibration damping, and insulation applications. Furthermore, it is also used to synthesize vinyl-containing silicone resins, which are commonly used in the formulation of high-temperature resistant coatings and electronic potting compounds, utilizing the reactivity of vinyl groups to enhance the crosslinking density and hardness of the coating film.

As a silane coupling agent, this compound has important applications in the composite materials and coatings industries. It utilizes the methoxy group to chemically react with the hydroxyl groups on the surface of inorganic materials (such as glass fiber, silica, and metal oxides) to form chemical bonds; simultaneously, it utilizes the vinyl group to react with organic polymers (such as epoxy resins and unsaturated polyesters). This “molecular bridge” effectively improves the dispersibility of inorganic fillers in the organic matrix, significantly enhances interfacial bonding, and thus improves the wet strength, water resistance, and mechanical properties of the composite material.

In the fine chemical industry, dimethoxymethylvinylsilane can also be used as a pharmaceutical intermediate or for the synthesis of specific organosilicon derivatives. For example, in the synthesis of molecularly imprinted polymers (MIPs), it is used as a monomer of silane coupling agents to construct materials with specific recognition properties. Furthermore, it can be used to prepare specific anchoring agents, flame retardant treatment agents, etc., to further optimize the surface properties and functionality of materials.
