The two-component polysulfide sealant is used for the construction , transportation, concrete prefabricated building materials and the sealing of construction joints. Advanced roads, Bridges, airstrips, underground pipes, connection seals at the head, and expansion joints and deformation joints of tunnels and buildings.
Product Features
1.Adhesiveness: polysulfide sealant has good adhesion to cement, steel, glass, wood, natural stone, etc.
Half of the construction and water conservancy works should use low modulus, high elongation of polysulfide sealant, its bond strength
2.Water resistance: the effect of polysulfide sealant on seawater, tap water and distilled water is stable, and the weight of sea water (including salt) is minimal. 3.Acid and alkaline energy: strong acid and alkali.
But the dilute inorganic acid, alkali and various kinds of salts are stable.
4.Heat aging properties: polysulfide sealant thermal aging performance is good, can be in for a long time - work under the condition of 40 ° ~ 120 °.
5.Good radiation resistance: the performance of polysulfide sealant is very good
6.Non-toxicity: although the liquid polysulfide sealant is a little sulfurous odor, it is gradually absorbed by the packing after curing.
7.Good air tightness: not only has good elasticity, but also its air tightness is best in elastic sealant
