Product Description

Our company according to the coastal area and high saline alkali area,or to the building waterproof project that has the special request of saline alkali resistant performance ,developed a kind of waterproof membrane content with polyester felt as base material,using styrene butadiene styrene (SBS) petroleum asphalt modified,covered with surfance materials,adding salt tolerant basic functional additives

Product features
1.Has excellent salt tolerance performance,Especially suitable for coastal areas and high saline alkali areas,or the building waterproof project that has the special request of saline alkali resistant performance. 2.Have good weather resistance,tensile property,high elongation,good wear resistance,excellent workability.

Where to use
1.Coastal areas and high saline alkali areas of the building roof, basement, tunnel, water conservancy and other works of waterproof, moisture, seepage.
2.the building waterproof project that has the special request of saline alkali resistant performance.

Storage and transportation
Avoid the sun and rain,storage temperature should be 4℃-45℃.Storage and transportation should be vertical,no more than two storeys high,prevent inclination and cross pressure,and covered with poncho.
