    3M™ Air & Vapor Through Wall Flashing Tape 3015TWF

    Description: The 3M™ Air & Vapor Through Wall Flashing Tape 3015TWF is a high-performance, self-adhered flashing tape designed for use in through-wall applications. This impermeable membrane features an aggressive, high-tack acrylic adhesive that ensures excellent adhesion without the need for a primer on most construction surfaces.

    Key Features:

    • Exceptional Durability: Offers outstanding puncture and abrasion resistance.
    • Versatile Adhesion: Adheres to concrete, concrete block, anodized aluminum, galvanized metal, exterior gypsum sheathing, and plywood.
    • No Primer Needed: Primer is not required for most applications, simplifying installation.
    • Flexible in Low Temperatures: Remains flexible even at low temperatures, making it suitable for various climates.
    • Unique Adhesive: Adheres to damp surfaces that have not absorbed water, such as metals, glass, and plastics.
    • Sealant Compatibility: Compatible with many building sealants, including polyurethane, silicone, and silane-terminated hybrid sealants.
    • UV Resistant: Resists UV exposure for up to 12 months, ensuring long-lasting performance.

    Technical Specifications:

    • Service Temperature: -40°F to 240°F (-40°C to 116°C)
    • Application Temperature: 0°F to 150°F (-18°C to 66°C)
    • Total Tape Thickness: 0.4 mm (15.5 mil)
    • Film Thickness: 0.19 mm (7.5 mil)
    • Elongation at Break: 600%
    • Tensile Strength: 7 MPa (>1000 lb/in²)
    • Water Vapor Transmission: 0.05 US Perms
    • Puncture Resistance: 170 N (>38 lb)

    Application Instructions: For optimal adhesion, ensure surfaces are clean, free from dirt and debris, and have not absorbed water. Concrete must be cured for a minimum of 7 days before application. Block or brick walls should have mortar joints stuck flush. For difficult-to-stick surfaces, test adhesion before application. If needed, use 3M™ Hi-Strength 90, 3M™ Hi-Strength 94 ET Spray Adhesive, 3M™ Scotch-Weld™ Holdfast 70, or 3M™ Fastbond™ Contact Adhesive 30NF to prime the substrate.
