Silicone caulk can be used as a basic sealant against water and air penetration.
Silicones (/'sIlIkən/) are
polymers that include any inert, synthetic compound made up of repeating units of
siloxane. This is a functional group of two
silicon atoms and one
oxygen atom frequently combined with
carbon and/ or
hydrogen. They are typically heat-resistant and
rubber-like. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, and thermal and electrical insulation. Some common forms include
silicone resin, and silicone caulk.
 Silicone is also used for cosmetics. Silicone has very little to do with the
