One-side sticky self-adhesive bitumen waterproof membrane for 1.5, 2.0, 3.0 mm
Description SAM-920 is a modified bitumen base sheet consisting of styrene-butadiene- styrene (SBS) compound modified asphalt covering with different upper separated materials, no fiber and underside with silicone antisticking layer. According to different upper surface, it can be three types: HDPE film surf- acing (SAM-920PE), Aluminum foil surfacing (SAM-920AL) and Non-film surfacing (SAM-920N). There have three kinds of thickness: 1.2 mm, 1.5 mm and 2.0 mm.
Where to use
Swimming pools, fire pools and reservoirs;
Subways or tunnels;
Open fires forbidden construction areas;
SAM-920PE can be used in non exposed roofs and undergrounds;
SAM-920AL can be used in all kinds of exposed roofs;
SAM-920N can be used as an auxiliary material or bonding material between two incompatible places.
Advantages
Self adhesive, safe and environment-friendly;
Excellent flexibility in low temperature and elongation;
Strong adaptability for substrate shrinkage, deformation and cracks;
Strong self healing ability for penetration and cracks;
Lasting bonding and sealed performance;
Excellent water resistance.
Standards ASTM D1970
Packaging SAM-920 material is packed in rolls with plastic bags or cartons.
Above quantities are indicative only. We can produce it according to your demands.
Storage and Transportation SAM-920 material should be stored in well-ventilated shade place and protected from sun or rain. The temperature in stored places can not be higher than 50° C. It can not be put in more than two levels. If packed by cartons, it can not be put in more than five levels.
Application System Yuhong adhesive waterproof system includes substrate, primer, membrane waterproof underlayment, protection layer. Yuhong also provide a complete line of compatible accessories and components, including primers, pipe clamps, terminal battens and screws.
Surface Preparation Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and uneven places need to be filled by polymer mortar.
Priming Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
Membrane laying After substrate treating agent drying, lay SAM-920 material according to application designs.
Sealing, fixing and constraining on vertical surfaces On vertical surfaces, fix with metal battens and seal with sealants for membranes.
Application on protection layer After membrane laying, apply on protection layer according to waterproof layer design.
