Definition
Silicones are synthetic polymer containing alternate silicone and oxygen atoms as its backbone. Silicones are made from silicon (a metal obtained from silica sand) and methyl chloride (an organic compound) in a process known as the direct process. The Silicone sealant in the uncured state normally looks like a thick paste or cream. After curing the paste turns into an impressive rubber.
Applications
Silicone sealant are used as a form-in-place gaskets for engine & transmission applications, sealing of exterior joints, aquarium joints bonding, sealing of bath tubs, construction and glazing application, electrical potting & encapsulation, mould making, etc.
Curing Mechanism
RTV silicone systems use humidity or moisture in the air during curing and cannot be accelerated using heat (excessive heat in the curing process can be detrimental). Small amounts of by-product are also produced. The cure process will only take place if the material is open to the atmosphere and curing will be adversely affected if access to humidity is removed prior to the completion of the cure process.
Provided product types
One component RTV silicone sealant
Two component RTV silicone sealant
