COPPERHEAD SEaM TAPE

COPPERHEAD Roof Flashing & Seam Tape is a high-temperature self-adhered waterproofing tape made with an advanced butyl rubber adhesive combined with a durable tri-laminate high-density polyethylene facer. It is designed specifically for use as a roof deck seam and flashing detail tape. Its 100% butyl adhesive provides the ultimate bond to plywood, OSB, DensDeck, ridged foam insulation, metal, and other common roof deck materials. Copperhead tape can be used under all standard sloped roof coverings including slate, tile, cedar, metal, and asphalt shingles.

Copperhead tape features an embossed top surface that provides improved slip-resistance at the same time as offering an ideal surface that adheres strongly to itself and most substrates without the need for heat or special primers.

  • High-temperature stability for environments up to 260°F(126.7°C).
  • Adhesion up to 3X Stronger than standard modified bitumen products.
  • Extremely low installation temperature -4°F(-20°C) and rising.
  • The advanced adhesive formulation will not crack or dry out and offer up to 18 months of shelf life without significant adhesive strength reduction.
  • Chemically compatible with low slope roofing materials such as EPDM and TPO.
  • Self-sealing around roofing fasteners. The product meets and exceeds ASTM D1970.
  • Watertight bonds without special treatment or requirement for primers.
  • All temperature, all-climate performance -40°Fto 275°F (-40°C to 135°C)
  • Easy to remove silicone treated release liner.
    UV Exposure rating up to 180 days.
