About
Polysulphide is an elastomer that is widely used as a sealant in construction and road works. It can also be used as an adhesive in some applications.
It is used for sealing expansion joints where large movements are expected and for joints between diverse construction materials. It is suitable for sealing joints subjected to vehicular traffic and is chemically resistant to water, fuels, oils, and solvents.
Exhibits excellent elastic behaviour at sub-zero temperatures (upto -40 °C)
Polysulphide polymer results from the polycondensation of bis-(2- chloroethyl-) formal with alkali polysulfide.
Properties
Sealing of expansion and contraction joints.
Jointing applications in concrete roads, bridges, subways, flyovers & airport runways.
Chemical curing. Oxidative curing.
The liquid polysulfide are polymers of bis (ethylene oxy) methane containing di sulfide linkages terminated with mercaptan groups. When polymerized by mixing with an oxdizing agent, water is produced.
