TN - 851 waterproof two-component polysulfide sealant and two-component polysulfide sealant, appearance is fine and uniform paste or viscous body, suitable for all kinds of cement building distortion seam, regardless of the deformation cracks of the building is standing seam, sewn or sewing, are applicable, the sulfur seal was painted on the structure of the vertical seam or sew later, there will be no sealant is flowing from the construction joint fall off phenomenon, but just stick to the above, so, not droop type two-component polysulfide sealant is particularly suitable for building standing seam or seam roof construction, the droop type two-component polysulfide sealant oil resistance, water resistance, air resistance, uv resistance, impact resistance, high resistance to friction, low temperature (- 50 ℃ to 120 ℃) , no pollution; Belong to low modulus, high elongation, apply to the civil engineering, large-scale water conservancy projects, water plant, large sewage treatment plant, water supply and drainage, water conservancy projects, and construction outside hangs Taiwan and so on concrete engineering, has a good bonding effect. The deformation joint has the function of thermal expansion and shrinkage, deformation shift synchronization and coordination. A two-component polysulfide sealant and two-component polysulfide sealant, the quotation list of two-component polysulfide sealant and two-component polysulfide sealant is a kind of the waterproof performance is very stable product, based on the molecular has an - SH, at the end - SS - key chain of liquid polysulfide rubber as the main agent, metal peroxides as curing agent type two-component sealing material, two components given according to the proportion of mixture, temperature curing often form rubber elastomer. As a waterproof sealing material, it is widely used in civil engineering.
