asphalt waterproof roofing felt

     asphalt waterproof roofing felt Introduction This  series is a kind of waterproof asphalt roofing felt that high polymer modified- rubber mixes with many surfacing materials, and it is very environmentally friendly product.   Advantages Excellent waterproofness;   Unique creep properties and self-healing capability which can recover by itself;   Strong adhesion which can targeted the leakage in localized areas;   Tight joints, good extensibility;   Good stability and corrosion resistance, lasting effect.     Applicable scope   Basement, metro, tunnel, pool, roof.   HDPE film and two-sided self-adhesive membrane are used for non exposed roofs while the aluminum foil membrane is used for exposed roofs.   Controller link 1. Nianba self-adhesive membranes (normal temperature /low temperature)   2. Supporting base primer   A: solvent base B: emulsion   3. Supporting sealant   4. Supporting construction tool   Construction *Safe, pollution-free.   *Two-sided self-adhesive membrane can be used as waterproof layer and complex use to compose multiple waterproofing systems.     Performance index
