Self-adhesive Polymer Modified Asphalt Waterproofing Roll-roofing Material

Detail

Product Description.

Self-adhesive polymer modified asphalt waterproofing membrane is a very promising new waterproofing materials. At home and abroad has just risen, the flourishing. The coil has impermeability, low tenderness, resistance to deformation and good self-healing properties, and easy construction, can improve the speed of laying, speed up the progress of the project. In Guangzhou, Shenzhen, Nanjing, Xiamen, Shanghai and other places in the industrial plant roof, underground engineering, Antarctica Great Wall Station, Zhongshan Station, etc. to promote the use of a good waterproofing effect, by the construction, design and construction units praise. Although, the product's market share is not large, but has become the "new favorite" in today's waterproofing materials.

Product Features.

1. The coil itself has adhesion, construction does not require hot melt or with the help of adhesive.

2. High tensile strength, high elongation, strong adaptability to shrinkage deformation and cracking of the grass-roots level.

Solid full adhesion effect with the grass-roots level, to ensure no cascading, no leakage.

3. Good water tightness, excellent self-healing ability for nail rod penetration or fine cracks produced under external stress.

4. Construction without solvent and fuel, avoiding environmental pollution and saving labor and energy.

Scope of application

Suitable for industrial and civil building roof, wall, kitchen and bathroom, basement, pool and bridge, subway, tunnel and other projects of waterproofing and impermeability

Double-sided self-adhesive coil is suitable for the protection of metal containers and pipes against corrosion.

Particularly suitable for waterproofing projects that should not use open fire.

Implementation standard: GB23441-2009
