Butyl Self-Adhesive Waterproof Tape is a high-performance sealing and waterproofing material made from butyl rubber as the main raw material, combined with tackifying agents and reinforcing fillers through advanced extrusion technology. It is available in pure butyl rubber tape and aluminum foil laminated butyl tape versions.
The tape features permanent adhesion and non-curing properties, maintaining flexibility and sealing performance under long-term temperature changes. After application, it can follow minor movement and deformation of the substrate while providing excellent waterproof, airtight, and dustproof protection.
With strong self-healing capability, the material can automatically seal minor cracks and punctures, preventing water leakage and air penetration. The cold-applied installation method requires no heating, primer, or additional adhesive, allowing fast and convenient application on various surfaces including metal, concrete, glass, PVC, aluminum, tiles, and waterproof membranes.
It is widely used for roof repairs, metal roof joints, pipe sealing, construction joints, and various waterproofing maintenance applications.
Key Features & Benefits
When waterproofing projects require fast repair, strong sealing, and long-term flexibility, QINGYUAN Butyl Self-Adhesive Waterproof Tape provides a reliable solution for joints, cracks, and complex waterproofing details.
Permanent butyl rubber adhesion remains flexible without hardening, cracking, or losing sealing performance over time.
Self-healing sealing technology automatically closes minor gaps and punctures to prevent water and air leakage.
Excellent multi-surface adhesion bonds firmly with metal, concrete, glass, PVC, aluminum, tiles, and waterproof membranes.
Cold-applied installation requires no heating, primer, or additional adhesive, improving construction efficiency and safety.
Excellent weather resistance provides long-term protection against rain, UV exposure, acids, and environmental aging.
Wide temperature resistance from -40℃ to 80℃ maintains stable performance in extreme climates.
Strong waterproof and airtight sealing performance provides protection against moisture, dust, and leakage.
Aluminum foil surface option improves UV resistance and is suitable for long-term outdoor exposure.
Ideal for metal roofs, joints, pipelines, cracks, renovation projects, and waterproof detail reinforcement.

Standard Construction Process
Professional cold-applied installation methods ensure strong adhesion, reliable sealing, and long-lasting waterproof protection for repair and joint sealing applications.
Base Surface Preparation
Clean dust, oil stains, rust, dirt, and loose materials from the application area. Ensure the surface is dry and stable before installation.
Tape Selection & Cutting
Select the appropriate tape width according to the crack or joint size. Reserve sufficient overlap area on both sides for reliable sealing.
Release Film Removal & Positioning
Remove the release film from one end, align the tape with the repair area, and gradually apply while removing the film.
Rolling & Air Removal
Press the tape firmly with a rubber roller or scraper from the center outward to remove trapped air and ensure complete bonding.
Joint Reinforcement Treatment
For wider cracks or important connection areas, apply additional tape layers and reinforce overlap sections with extra pressure.
Final Inspection & Protection
Allow sufficient bonding time after installation. Check the sealing condition and protect the tape from mechanical damage during the initial curing period.
