self-adhesive bitumen waterproof membrane for roof
1. Product Instruction:
Speed grams of self-adhesive polymer modified bitumen waterproofing membrane is as SBS synthetic rubber, high grade road asphalt and tackifier as base material, using polyester film (PET), polyethylene (PE) film, aluminum foil or coated silicon isolation membrane for the surface material, the lower surface coated with silicone coated isolation membrane for self-adhesive polymer anti sticking layer made of modified asphalt waterproofing membrane without tire.
2. Product's Performance:
1) Cold construction: no fire use, not suitable adhesive, energy saving, environmental protection, low carbon economy,
2) The bonding performance excellence, in viscoelastic state for a long time, to ensure the integrity of the waterproof layer;
3) Gao Yanshen performance, excellent shear strain;
4) Excellent low temperature performance;
3. Technical Specification:
