Usage

General Description

(METHACRYLOXYMETHYL)METHYLDIETHOXYSILANE is a chemical compound with the molecular formula C13H26O4Si. It is a silane coupling agent that is commonly used in the production of polymers and composite materials, where it acts as a coupling agent to improve adhesion between inorganic materials, such as glass, and organic polymers. It contains a reactive methacryloxy group, which allows it to undergo polymerization reactions, making it useful in the production of polymer coatings, adhesives, and sealants. It also contains two diethoxy groups, which can undergo hydrolysis to form silanol groups, allowing it to bond to inorganic surfaces. This makes (METHACRYLOXYMETHYL)METHYLDIETHOXYSILANE a versatile and valuable chemical in the field of materials science and manufacturing.
