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 Packing, storing, shelf life and transport Available packing sizes vary from 25 g to 25 kg, packed in lacquered coated aluminium tubes, HDPE cartridges and epoxy coated MS drums. Store products at room temperature (20C to 35C). Shelf life can vary from 4 - 12 months. They are safe to transport by road, air and sea.
