Multi-Component, Polysulphinde Sealant
Download Data SheetEstoseal T600 is a multi-component, low modulus, chemical cure polysulphide joint sealant developed specially for dynamic joints. It is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough rubber like seal. Estoseal T600 exhibits excellent adhesion to most surfaces and has good resistance to most chemicals and weathering conditions.
Sealing movement joints in building and civil engineering structures, including superstructures, reservoirs, floors, basements and subways.

Joint sealing slots in concrete should be accurately formed and must be dry, sound, clean and free from dust. Remove all dust and laitance by grit blasting or grinding. Avoid polishing the joint sides when grinding. The prepared sealing slot should be blown out with dry, oil-free compressed air.
Ensure that any expansion joint filler is tightly packed in the joint and at the required depth to provide the specified seal dimensions. Before sealing insert a cord or bond breaker caulked tightly into the base of the sealing groove to prevent sealant adhering to the base of the slot.
Primer Estop Primer S8 should be applied to clean, dry surfaces prior to installation of backer rod or bond breaker tape.
Mix all the base component with curing agent by using a hand held, slow speed drill (300 to 400 rpm). Mix for approximately 3 minutes until evenly and thoroughly mixed.
In cold weather, Estoseal T600 mixes more easily if stored overnight at room temperature.
When mixed, the sealant may be loaded into Barrel Gun after removing the nozzle end cap and pulling back the plunger rod. The nozzle cap is then replaced ready for application. In wider joints of 25 mm and above, the mixed sealant may be poured directly from the tin by bending the side to form a pouring lip. Apply mixed sealant into the sealing slot so that the finished level of the seal is recessed below the trafficked surface as specified.
Estoseal T600 with Estop Primer S8 is not compatible with bituminous surfaces.
