waterproof sealant tape 10cm by 500cm

Aluminum butyl tape is a heavy-duty, self-adhesive repair material featuring a flexible butyl rubber sealant protected by a durable aluminum foil backing. It creates an instant, waterproof, and heat-resistant seal for roof leaks, cracked pipes, gutter damage, and water tanks. [1, 2, 3, 4]
Key Advantages

• All-weather durability: Resists UV rays, extreme temperatures, and heavy rain without cracking or drying out.
• High flexibility: Stretches and conforms easily to uneven surfaces, corrugated metal, and sharp corners.
• Strong adhesion: Bonds aggressively to almost any material, including concrete, glass, metal, wood, and plastic.
• Instant repair: Stops water flow immediately upon application without needing any curing time.
  Limitations to Keep in Mind
• Not for high pressure: It cannot seal pipes under high water pressure (like main water supply lines).
• Extremely sticky: Once it touches a surface, it is very difficult to reposition. Align it carefully before pressing down.
• Surface-dependent: It will fail if applied over wet, muddy, or frozen surfaces. [1, 2, 3, 4, 5]
