RTV silicone rubber - 11099-06-2

Key Functions: Plasticizers & Polymer

In general, RTV silicone rubber is a room temperature vulcanized silicone rubber, which requires crosslinking at elevated temperature to produce the cured rubber. It has a relatively low molecular weight and typically consists of a viscous hydroxyl-terminated silicone resin and tetraethyl orthosilicate (TEOS), the crosslinking agent. When reacted together, they form silicone rubber (Honey Silicone 2011). The CAS number of 11099-06-2 refers to the tetraethyl orthosilicate polymer according to ChemIDplus and Pharos databases. It is considered by Environment Canada as a UVCBs-organic substance (Environment Canada 2013).
