    Sinomaco Self-adhesive Bitumen Waterproofing Membrane also called self bonding bitumene membrane is a kind of widely used waterproofing bitumen membrane both for explosure and non explosure waterproofing construction works. It is made of self-adhesive polymeride modified bitumen as the base materials and covered with PE film, silicone release film, fine sand, PET film or aluminum film for roofing waterproofing. it can be one side adhesive, like roofing bonding aluminum covered membrane or two side adhesive for non explosure use. It can be made without of any reinforcement layer called N type or it can be reinforced with polyester fiber to be more strong called PY 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. Excellent 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 typhoon 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.
