Silanmonomerer

Silanmonomerer are the fundamental building blocks for silicones. These are organosilicon compounds characterized by at least one silicon-carbon bond. The general formula often features silicon bonded to organic groups, such as methyl, ethyl, or phenyl, and one or more hydrolyzable groups, typically alkoxy (e.g., methoxy, ethoxy) or acetoxy. These hydrolyzable groups are key to the polymerization process. When exposed to moisture, the hydrolyzable groups react with water, leading to the formation of silanol (Si-OH) groups. These silanol groups are highly reactive and can then condense with each other, releasing water molecules and forming siloxane (Si-O-Si) bonds. This condensation reaction is the basis for the formation of silicone polymers, which can range from linear chains to highly crosslinked networks, depending on the type and functionality of the silanmonomerer used. The variety of organic groups attached to the silicon atom in the monomer influences the properties of the final silicone material, such as its flexibility, thermal stability, and chemical resistance. Silanmonomerer are thus essential intermediates in the production of a wide array of silicone products, including sealants, adhesives, lubricants, and coatings.
