Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
This makes silicone rubber one of the elastomers of choice in many extreme environments. Silicone is considerably more permeable to gasses than most other rubbers which limits its use in some areas. Silicone rubber is highly inert, does not react with most chemicals, and does not participate in biological processes, allowing it to be used in ...
Silicone resin with R = CH 3, H or OH. Silicone resins are a type of silicone material which is formed by branched, cage-like oligosiloxanes with the general formula of R n SiX m O y, where R is a non-reactive substituent, usually methyl (Me = −CH 3) or phenyl (Ph = −C 6 H 5), and X is a functional group: hydrogen (−H), hydroxyl (−OH), chlorine (−Cl) or alkoxy (−O −).
