Silicone sealants

Silicone sealants are generally polysiloxanes, i.e. a silicon-oxygen chain to which organic groups, such as methyl groups, may be bonded.

 

Silicone sealants cure at room temperature due to the presence of moisture. These sealants are known as RTV (Room Temperature Vulcanisation) sealants.

We classify RTV silicone sealants into three main families based on the type of product released during cross-linking:

  • Acetic silicones;
  • Neutral alkoxy silicones;
  • Neutral oxime silicones.

 

Silicone sealant forms a perfect seal against liquids, and is compatible with a broad range of substrates (good adherence to a large number of materials: glass, metals, plastics…), which makes silicone sealant ideally suited to outdoor applications.
