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.

Water Treatment DEHA is used in Water Treatment Chemical Formulations for controlling corrosion in boiler very effectively due to its property of oxygen scavenge scores over conventional hydrazine hydrate since it is far less toxic and meets the standard for disposal of blow offs without any difficulty giving good protection against corrosion at the same time. Polymerization DEHA's powerful free radical scavenging ability coupled with its moderate volatility and relatively low order of acute toxicity makes it an ideal "po Polymer "/ vapour phase inhibitor for olefins or styrene monomer storage & recovery system. Because of its capability of inhibiting polymerlzatlot the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, isoprene and other monorr containing a reactive double bond. â?¢ Photographic Chemicals DEHA has reducing property, so it is used as an auxiliary chemical photographic developer for instant colour photos. Also, DEHA is effective in stabilization of image and in the prevention of discolouration. Decolourisation Phenol and Phenolic antioxidants can be decolourised with DEHA. Inhibitors DEHA also can be used as a colour stabiliser of monoalkyl phenol. Silicon Rubber DEHA can be used as a raw material for the hardener of the Silicon Sealant and coating agent. Storage Can be stored and handled in equipment made of stainless steel of Type SS304 or SS316 or steel lined with glass, polypropylene or polyethylene Storage in mild steel equipment or containers is not recommended. DEHA drums should be stored in a cool and well ventillated area, away from sources of ignition. Forms two layers for concerntration from 33 to 87 wt %. Packing 25 kg, 180 kg net wt. in HMHDPE carbouys & drums . Health &Safety DEHA is irritating to skin,eyes and the mucous membrane. In case of contact,affected area to be washed with plenty of water for atleast 15 minutes. In case of inhaltion,victim should be moved to fresh air and oxygen should be administered. In case of ingestion,victim should be made to consume copious quantity of milk and water. Medical advice should be sought at once. Personal protective equipment should always be used while handling.

Two-component polysulfide sealant, as known as a two-component, non-sag, premium polysulfide sealant, which is also called polysulfide sealant for building made up of liquid polysulfide rubber, and add tackifying resin, vulcanizing agent, accelerant and fortifier into it. It contains two components and it can vulcanize and crosslink by itself at room temperature. The two components have clear color difference, which makes the mixing more convenient. It can keep good air tightness and water resistance in continuous vibration and temperature changes. In addition, it has a good bonding effect for metal, concrete and other materials. Application The polysulfide sealant is suitable for outdoor or indoor and can be used to seal both static and dynamic joints: Used to caulk at concrete, building, and bridge. Used in anti-leakage caulking of various types of expansion joints, such as waterworks, swimming pools, reservoirs, power plants, dams, sewage treatment works and water supply and drainage systems and other projects. Used as the joints of precast concrete, and the seams of the glass and construction. Used in the seaming of metal siding, and the bonding of aluminum window frame. Using method Add component B and pigment into component A; Stir quickly up and down until it is well mixed; Wipe the mixed sealant in the site where is waiting for construction with a small shovel; Don´t soak and contact with water within 48 hours after construction. Note Component B should be fully added into component A, which will affect the curing time and plasticity; The available time of mixed sealant is 2 hours. So the sealant should be used up as soon as possible after preparation to avoid the paste curing; The surfaces waiting for construction must be clean, dry and frost-free, and must be free of oils, grease, paints, coatings, sealers, curing compound residues, and any other foreign matter that might prevent adhesion; Notice to avoid water and rain within 48 hours after construction.
