BXI Fluorocarbon Film Asphalt Waterproof Tape - 12 In x 32 Ft Self-Adhesive SBS Bitumen Flashing Sealant

Overview

BXI’s Fluorocarbon Film Asphalt Waterproof Tape combines high-performance materials into a self-adhesive flashing sealant designed to shield outdoor and semi-exposed surfaces. The roll measures 12 inches wide by 32 feet long and features a 0.05 inch thickness, delivering durable coverage with a weight of about 8 pounds. The formulation blends a white fluorocarbon surface with SBS polymer-modified rubber asphalt, creating a versatile membrane built to perform under shifting temperatures.

With a wide operating range from -4°F (-20°C) to 158°F (70°C), this tape is crafted to stay flexible and resilient as the weather changes. The white fluorocarbon film reflects sunlight, helping limit surface heat buildup, while offering strong tear resistance and UV stability. The product’s corrosion resistance and flame retardancy add to its value across various exterior and interior applications.

Weather resistance and durability

Key attributes come from the fluorocarbon film and the PVDF seam membrane. The PVDF surface enhances hydrophobic properties and reduces moisture intrusion, while UV reflection helps maintain material integrity over time. Expect robust performance against cracking in cold spells or warping in heat, thanks to the stable thickness and strong bonding.

• Durable outer fluorocarbon layer with high tear resistance
• UV-reflective white PVDF seam to minimize surface heat
• Corrosion resistance and puncture resistance for outdoor use
• Flame retardant characteristics add an extra layer of safety

Dual-layer waterproof design and crack filling

The tape features a two-layer approach: a top PVDF membrane forms a solid moisture barrier, while the bottom bitumen layer penetrates the substrate to seal and bond. Its elasticity helps maintain a watertight seal even as surfaces expand and contract with temperature swings. It also offers self-healing properties for minor surface damage, supporting ongoing protection without frequent rework.

• Top PVDF layer provides a strong moisture barrier
• Bottom bitumen layer penetrates to bond with the substrate
• Self-healing for minor repairs and sustained seal integrity
• Elastic formulation adapts to substrate movement

Versatile applications

Designed for outdoor durability, the PVDF surface resists stains and water roll-off, while the white finish complements many roof and wall profiles. Typical uses include sealing and crack filling on roofs, driveways, wood, gutters, sheds, metal structures, decks, concrete, basements, pools, pipes, chimneys, barns, HVAC, and roof shingles. It can even serve as a root barrier for certain DIY plant projects like planter boxes or green roof systems.

• Roof flashing and seam sealing
• Waterproofing around windows, vents, and skylights
• Crack filling on concrete, decks, and foundations
• Root barrier for DIY garden and green roof projects

How to use

Application is straightforward: clean and dry the surface, peel off the backing, and press the tape firmly in place. It adheres well to a range of substrates and shapes, including corners and curved areas. For very cold conditions, warming the tape slightly can improve adhesion. Store in a cool, dry place away from direct sunlight when not in use.
