Product Description
Product Features
1、Tackifying resin enhances the membrane's adhesion strength, ensuring a secure bond with the substrate.
2、Strong initial adhesion allows for secure bonding at temperatures above 5°C without the need for heating equipment, it is safety, environmental friendliness, and convenience.
3、The polyester mat (PY) reinforcement layer provides puncture resistance, abrasion resistance, and tearing resistance, increasing the material's strength and effectively protecting against damage and destruction from both the upper and lower 4、Excellent self-healing properties for fine cracks caused by external stresses.
5、 Durable adhesion ensures that the membrane does not detach or leak at the bonding points, with the lap joints having the same lifespan as the membrane itself.
6、High elongation (elongation rate ≥ 30%), with strong adaptability to substrate shrinkage, deformation, and cracking.
7、Does not flow at high temperatures and does not crack at low temperatures, offering a wide range of temperature for use (high temperature: 70°C, low temperature: -20°C).
How to Use :
Hot Adhesive Construction:
Construction Process - Subgrade treatment → Additional layer construction → Hot adhesive large area construction (laying the membrane) → Air expulsion and compaction → Water tightness test → Protective layer construction
Key Points of Construction -
1、Subgrade treatment: Clean the surface first; the subgrade should be solid, smooth, and clean.
2、Additional layer construction: For areas such as corners, pipe roots, gutters, and expansion joints, additional layer treatment should be applied by pre-cutting the membrane to the appropriate size and shape.
3、Large area construction: Use non-curing adhesive for hot adhesive waterproofing membrane composite construction, ensuring the non-curing coating thickness meets relevant specification requirements; roll out the waterproofing membrane while applying the non-curing adhesive.
4、Lap joint treatment: The lap width of the membrane should be 100mm; the lap area should be sealed separately, using the hot adhesive method. The lap joint should be filled with an Bitumen strip.
5、Water tightness test: Conduct the water tightness test according to the construction plan requirements.
6、Protective layer construction: A protective layer should be set up on the outer surface of the waterproof layer according to relevant specifications or design requirements.
