GP-SCM Quick Reaction Adhesive Strong Cross Membrane Self-adhesive Waterproofing Membrane
Quick reaction adhesive strong cross membrane self-adhesive waterproofing membrane,the main material is reactive adhesive add cross-laminated film.The binder contains active components for penetrating reaction and modify asphalt,it has good compatibility with asphalt, and has hydrophilic active groups. It can not only penetrate into the surface of concrete, but also react with silicate to form chemical cross-links, forming a firm and irreversible interface sealing reaction layer on the concrete base layer,to prevent water leakage.
The cross-film material is a specially designed 45-degree obliquely laminated high-density polyethylene film and a cross-laminated composite multi-layer film structure with high dimensional stability, thermal stability, bidirectional tear resistance, high strength and high ductility.
Quick-reaction strong cross-film self-adhesive waterproofing membrane (single-sided adhesive) is an isolation membrane on one side and a cross-laminated membrane on the other side, with a reactive adhesive in the middle.
Quick-reaction strong cross-film self-adhesive waterproofing membrane (double-sided adhesive) is a double-sided covered with isolation films on both sides and cross-laminated films sandwiched between reactive adhesive materials.
Application Scope
Used for waterproofing of non-exposed roofs, underground waterproof projects, and open-cut subways, tunnels, pools, canals and other projects. It is especially suitable for projects where open flames are not allowed. It uses cement mortar to bond to the base layer, and self-adhesive overlap is recommended between the rolls.
