Core Characteristics
Key Properties
- Excellent Waterproof & Airtight Performance: Forms a dense, permanent seal that completely blocks water, air, and moisture.
- Super Butyl Rubber Adhesion： Thick, soft, and highly sticky; bonds strongly to almost all materials without drying out.
- UV & Weather Resistance： Aluminum foil surface resists sunlight, aging, yellowing, cracking, and long-term outdoor exposure.
- Wide Temperature Resistance： Stable performance in extreme environments, generally -40°C to 110°C.
- High Flexibility & Malleability： Easily conforms to uneven, rough, curved, cracked, or irregular surfaces.
- Anti-Corrosion & Anti-Rust： Protects metal surfaces from rust and chemical corrosion.
- No Shrinking, No Cracking： Remains flexible over time; does not harden, shrink, or become brittle.
- Strong Sealing & Gap-Filling Ability： Automatically fills small holes, gaps, and cracks for instant leak stopping.
Common Applications
- Roof leak repair (metal, asphalt, shingle, flat roofs)
- Sealing gaps around skylights, chimneys, vents, gutters
- Window & door frame waterproofing
- RV, caravan, and boat seam sealing
- Pipe leaks, water tanks, and plumbing repairs
- Crack sealing on walls, concrete, and metal sheets
- Outdoor AC units, solar panels, and construction joints
- Rust prevention and surface protection for metal structures
Important Notes
-
Surface must be clean, dry, dust-free, and free of oil or loose paint
-
Press the tape very firmly to remove all air bubbles for a watertight seal
-
Best applied at temperatures above 5°C; cold weather makes butyl stiff
-
Not for structural or load-bearing repairs
-
Not designed for continuous full underwater submersion
