Silicone Coating

There are many forms of silicone used to form a silicone coating. This includes heat-cured types and room temperature vulcanising (RTV). Heat cured silicone is cured in a similar way to other rubbers using ovens and direct heat. RTV’s are not vulcanised with sulfur but instead are hardened with a catalyst from an initial viscous state.

When people think of silicone, the first thing that springs to mind are the types used in bathrooms, there are effectively RTV’s and are produced with fillers in order to keep the cost down for domestic use.

Other uses for silicone is as an adhesive. You will see this on our Tefsil range of products such as Tefsil 5 Adhesive. We also offer silicone coating on the surface on PTFE coated glass fabrics such as our product SIL-056.

Another interesting use for RTV silicone coating is as a bonding agent for the silica tiles used to protect against the intense heat experienced on the bottom of the space shuttle such as Atlantis.

Here are some key features of silicone rubber.
