The characteristics of self leveling two-component sealant:
1 adhesive: self leveling two-component polysulfide sealant for cement, steel, glass, wood, natural stone material has good adhesion. The general construction and water conservancy project should use the low modulus and high elongation of polysulfide sealant, the bond strength is more than 0.2Mpa, elongation is greater than or equal to 300%.
2, water resistance: Poly sulfur sealant on the sea water, tap water, distilled water is stable, in contrast to the sea (including salt) the weight of the smallest change.
3, acid and alkali resistance, self leveling two-component polysulfide sealant is not resistant to strong acid and alkali。 But the thin inorganic acid, alkali and salt is stable。
4, the heat aging resistance: the thermal aging property of polymer sealant is very good, but it can work for a long time at a temperature of 40 degrees Celsius to 120 degrees Celsius.
5, good radiation resistance: Poly sulfur sealant r_ ray resistance of the performance is very good。
6, non-toxic: Although liquid polysulfide sealant is sulfur smell smell, but after curing were gradually absorbed. The packing of polysulfide sealant by testing the L China environmental and Sanitary Engineering Research Academy of preventive medicine, D50 >20g / kg. according to the national standard of toxicity grade is non-toxic level.
7, good air tightness, self leveling two-component polysulfide sealant has good elasticity, and its tightness in elastic sealant is the best. At present after the hot melt butyl rubber adhesive known.
