1. High tensile strength, high elongation and elasticity, good adaptability to shrinkage deformation and cracking of the substratum.
2. Excellent initial viscosity and adhesive strength, which can limit the leakage caused by waterproof materials breakage in local range to avoid water flowing through waterproof layer.
3. High adhesive strength between waterproof sheet lap joints, to insure waterproofness tight and reliable.
4. Safety and environmentally friendly, the application of self-adhesive waterproof materials is simple and convenient, which can avoid open-flame working.
5. Due to ropiness property, the product self-healing function can availably repair cracking of the substratum.
