Sinomaco Self Bonding Bitumen Waterproofing Membrane is a kind of bitumen membrane with new technology which is made of self-adhesive polymeride modified bitumen as the base materials and covered with PE film, Aluminum film, fine sand or PET film. It can be made without of any reinforcement layer called non reinforced type or it can be reinforced with polyester fiber to be more strong called polyester type.
Product Feature
1. Strong self-adhesion, self-adhesion to the ground base, safe, environmentally friendly.
2. The construction is simple and quick, the wet base is Wet-laid method, and the dry base is dry-laid method.
3. Super strong adhesiveness, reliable and firm lap seam, The life of the seam is as long as the membrane.
4. Exnt heat and low temperature performance, suitable for use in cold and high temperature areas.
5. Integrate bonding, healing, sealing and extending functions.
Application Scope
1. Widely used in industrial and civil construction of roofing, basement, subway, tunnel, water conservancy, wood or metal structure roof and other waterproof and moisture-proof projects.
2. It is especially suitable for special industries such as oil depots, chemical plants, textile mills, and grain warehouses which are not allowed to use heat welding method to apply.
3. It is suitable for waterproof and antiseptic in the area of coastal tyon or seawater corrosion and large structural deformation.

Transportation & storage
1. Storage temperature is not higher than 40°C. The storage period is six months from the date of production, and it can still be used after it passes the inspection. The coils shall be placed horizontally and stacked in a height of not more than five layers to prevent tilting or lateral pressure.
2. The construction site shall have special warehouses stacked to prevent the sun and the rain. Special packing bag sealed packing, prevent sun and rain during storage and transportation.
