1. Product Introduction
SAM-921 wet-laid cross-laminated polyethylene membrane self-adhesive waterproofing membrane is a waterproof material composed of a strong sealing adhesive that reacts with cement mortar as the bonding and sealing layer, bonded onto imported cross-laminated strong film. The upper surface of this material is a cross-laminated strong film, while the lower surface is an easily removable release paper or release film. This material combines the excellent properties of cross-laminated film with good adhesion to cement mortar.

4. Product Features
1, This product uses Valéron strong cross-laminated polyethylene film from the USA, thus possessing the following excellent properties: strong puncture resistance, high tear strength against nail penetration, excellent tear resistance, high elongation, good dimensional stability, and superior low-temperature performance;
2, The strong sealing adhesive used in this product is made from a scientific formulation of selected asphalt and various additives, which provides excellent bonding performance with various substrates. When bonded to cement mortar, it forms a mechanical lock through physical adsorption and diffusion, ensuring a strong and durable bond.
3, Due to the strong creep resistance of the adhesive, it has a strong ability to adapt to substrate deformation, making it suitable for construction under various environmental conditions, providing good "self-healing" functionality. It compensates for the limitations of rigid waterproofing in concrete, achieving a dual waterproof effect of rigidity and flexibility.
4, This product is fully bonded with cement mortar and the building substrate, providing strong resistance to damage, excellent waterproof function, effectively preventing liquid water and water vapor from entering the structure; it requires no primer or heat fusion, poses no fire hazard, and does not require special treatment for uneven substrates, making the construction simple, safe, and environmentally friendly.
5. Application Range
Widely used in non-exposed surfaces of various buildings, underground and indoor projects, as well as waterproofing for open excavation subways, tunnels, water tanks, drainage channels, etc., especially suitable for projects where open flames are not allowed.
