Introduction:

1.      The quality of our polysulfide sealant is superior as tested by the Quality Supervision & Testing Center For Building Waterproof Material according to China standard JC/T483-2006. It’s also the top water-proof material home and abroad. In foreign developed countries, the polysulfide construction sealant is widely used in wall jointing of high buildings.

2.      Our polysulfide water-proof sealant is suitable for the jointing seal of water soaking buildings. For example, underground waterproof jointing, airport runway, water reservoir, sewage pool, underground construction and large water conservancy projects, etc.

3.      It has the features of aging resistance, durability, air tightness, waterproofness, good adhesiveness. 

Technical Performance:

1.       Polysulfide sealant for construction: Non-drooping type, high elongation and low modulus, it becomes high elastomer rubber-like after solidification.

2.       Mix proportion: prepolymer (A) : hardener (B) = 100 : 0. The proportion is subject to change along with the temperature, season and terrain. The quantity of hardener can be used to adjust the time. The variation range of B is between 8-12.
