Butyl-Aluminum Tape 1.2mm Heavy-Duty Sealing for Aged Color Steel Roofs
Product Description
| Roduct Name | Aluminum Foil Butyl Rubber Waterproofing Membrane |
| Material | Butyl |
| Color | Silver |
This premium self-adhesive membrane features a three-layer composite structure: a butyl rubber core laminated to a stable aluminum foil carrier, available in single or double-sided formats. It forms an instantaneous bond with diverse substrates, proving exceptionally effective for sealing color steel tiles and bridging roof cracks. The material demonstrates superior weatherability, resisting UV degradation and water penetration to maintain an enduring seal. Its defining property is lifelong flexibility, allowing it to absorb vibration and perfectly adapt to substrate thermal movements without compromise. As a 100% solvent-free solution, it ensures zero shrinkage, emits no harmful substances, and provides an environmentally secure seal.
Product Characteristics
• Autonomous Sealing Bond: Penetrates deeply into concrete pores, actively expanding upon water contact to autonomously seal micro-cracks.
• Dynamic Structural Compliance: Combines powerful adhesion with high elasticity and elongation, ensuring full compatibility with substrate movements.
• Long-Term Environmental Resistance: Excellent weatherability, chemical and UV resistance, with a designed service life of up to 20 years.
• Green Low-Temp Application: Suitable for cold application at -5°C; solvent-free and odorless for safe, environmentally friendly installation.

Construction applications
• Surface Preparation: Eliminate all sharp protrusions and foreign matter to achieve a clean, sound substrate.
• Primer Application (if required): On aged color steel surfaces, apply the designated water-based, rust-inhibitive primer.
• Main Membrane Installation: Align the membrane with the guideline and consolidate it using a rubber roller, moving forward and sideways to evacuate trapped air.
• Lap Seam Treatment: Ensure all overlapping seams are thoroughly bonded by applying firm pressure with a weighted roller.
• Detail Reinforcement: Execute all necessary detailing work in strict accordance with the applicable specification requirements.
Scope of Application
• Ideal for General Waterproofing Applications: Suitable for roofing, underground structures, construction joints, and perimeter sealing in waterproofing systems.
• Applied in Civil Engineering Projects: Used for watertight sealing of construction joints in viaducts, metro systems, and underground tunnels.
• Designed for Metal Roof Systems: Delivers sealing, cushioning, and weather resistance for profiled metal sheet and panel connections.
• Suitable for Multi-Material Bonding: Ensures durable adhesion between substrates like concrete, timber, plastics (PC, PE, PVC), and elastomers (EPDM, CPE).
• Engineered for Critical Waterproofing Zones: Maintains seal integrity at joints, terminations, and complex contours in waterproof layers.
• Integrated in Building Systems: Used for sealing openings, vibration damping between slabs, and airtight ductwork installation.
• Deployed for Repair & Maintenance: Effectively addresses roof leaks and seals seams in metal buildings, gutter systems, and storage structures.
