Butyl Rubber Waterproofing Sheet – High Bonding, Easy Application
Product Description
| Roduct Name | Aluminum Foil Butyl Rubber Waterproofing Membrane |
| Material | Butyl |
| Color | Silver |
Butyl rubber waterproofing membrane is a single or double-sided self-adhesive sheet primarily composed of butyl rubber, coated on reinforced aluminum foil and corrugated aluminum foil. This product exhibits strong adhesion to surfaces of various materials, making it particularly suitable for color steel tiles and roof cracks. It features excellent weather resistance, anti-aging performance, and waterproof capabilities, effectively sealing bonded surfaces. Functions like shock absorption and protection remain uncured throughout its service life, thus providing excellent follow-up adaptability to the thermal expansion, contraction, and mechanical deformation of the bonded surface. Completely solvent-free, this product does not shrink or emit toxic gases, serving as an eco-friendly solvent-free waterproof sealing and adhesive material.

Product Characteristics
- Unique bonding creep property: Bonds with concrete, fully penetrates concrete pores to prevent water leakage caused by concrete cracking.
- Excellent mechanical properties: High bonding strength and tensile strength, with strong elasticity and ductility.
- Stable chemical properties: Superior chemical resistance, weather resistance, corrosion resistance, and UV (sunlight) resistance, boasting a service life of up to 20 years.
- Simple installation, safe and eco-friendly: Free of volatile substances, non-toxic and odorless. Installable at a low temperature of -5°C; cold-bonding construction is safe, eco-friendly, convenient, and efficient.

Construction applications
- Substrate Preparation: Clear protruding sharp edges and debris from the substrate;
- Primer Application (if required): Aged color steel plates need to be coated with the matched water-based "rust-inhibitive primer";
- Large-area Installation: Align the membrane with the reference line, and roll forward and outward with a rubber roller to expel air;
- Overlap: Use a pressure roller to ensure tight overlap bonding;
- Detail Treatment: Reinforce detail processing in accordance with specification requirements;

Scope of Application
- Roof waterproofing, underground waterproofing, waterproof treatment of structural construction joints and short edge laps, or detail treatment of pre-applied waterproof membranes;
- Sealing and waterproof treatment of construction joints in elevated, subway, and tunnel structures within municipal engineering;
- Airtightness, waterproofing, and shock absorption at joints of color-formed plates and sunlight plate engineering joints;
- For bonding cement, wood, PC, PE, PVC, EPDM, and CPE materials;
- Applied to waterproof and airtight treatment of joints, termination parts, and special-shaped sections in waterproofing projects;
- Applied to airtight waterproof treatment of civil residence doors and windows, shock absorption and bonding sealing between floors, airtight waterproof treatment of ventilation ducts, and architectural decoration;
- Treatment for metal plate roof and cement roof leakage; Sealing treatment at overlaps between steel roof color steel plates and lighting boards, as well as gutter joints, steel warehouses, granaries, and cabinets.
