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.
High modulus poly sulfur waterproof sealant main use and use restriction:
The glass curtain wall, stone (marble, granite curtain wall), aluminum curtain wall, glass roof and bonding structure of metal structure of the hollow glass sealing; two bonded seal; high-rise building and industrial application of sealing and bonding; other types of construction and industrial sealing.
Not for all ooze fat, plasticizer and solvent materials, such as surface oiled wood; not for poor ventilation places; not frost, damp, soggy surface; the material surface temperature can not exceed 40 DEG C during the construction; and polysulfide rubber mixed use.
