Product Description
Product Name | Self Adhesive Waterproof Membrane |
Material | Bitumen |
Color | Black,silvery |
Engineered as a premium-grade membrane for outstanding field performance in a wide range of application scenarios, the Bitumen Self-Adhesive Waterproof Membrane is composed of a high-strength co-extruded protective layer, advanced modified bitumen compound, and a backing release liner that safeguards the adhesive properties. When installing, the release liner can be easily removed, allowing the modified bitumen to securely adhere to substrates made from different materials.
