Request Information
Millennium EPDM Seam Tape is an extruded, vulcanized, black pressure sensitive rubber adhesive tape designed to provide high strength, watertight seams for single ply EPDM roofing membranes. Millennium EPDM Seam Tape is soft and tacky providing a quick grab onto EPDM field membranes, yet possesses high initial strength. Millennium EPDM Seam Tape also exhibits excellent adhesion to polar and nonpolar substrates such as glass, metals, wood, concrete, masonry and some plastics.

Basic Use
Millennium EPDM Seam Tape is designed for field splicing of EPDM membranes.

Specifications

Surface Preparation

 N/A All work surfaces should be clean, dry, and free of dirt, dust, debris, oils, un-adhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven. If necessary, clean the surface to receive the Millennium EPDM Seam Tape with an approved EPDM membrane cleaner.

Safety

 N/A Prior to working with this or any product consult product label and Material Safety Data Sheet (MSDS) for necessary health and safety precautions.

Limitations

 N/A
  • Do not use for detail flashing applications.
  • Talc, dust, oil, ice, snow, or wet conditions inhibit good adhesion. Clean and dry surfaces are necessary for proper installation.

Storage and Shelf Life

 N/A Store material in original unopened packaging at temperatures between 40 °F-110 °F. Shelf life is 12 months when stored as recommended.

Applications

 N/A
  1. The entire surface where Millennium EPDM Seam Tape will be applied must be cleaned and primed.
  2. Mark the membrane where the edge of the splice occurs and then fold the top portion back. Apply EPDM primer to both sides of membrane using the supplied scrub pad. Scrub the membrane thoroughly while the primer is wet moving up and down the seam area. NOTE: Use caution when installing at temperatures below 40 ºF (5 ºC) to prevent blushing of EPDM primer (formation of condensation on surface of primer).
  3. Allow the primer to dry to the touch (no material transfer, typically less than 20 minutes). Dry time will vary depending on ambient temperature and humidity.
  4. Position the Millennium EPDM Seam Tape over the primed splice area along the marked edge. Press in by hand. Verify that approximately 1/8” (0.3 cm) of tape extends beyond splice edge.
  5. Roll the top surface of the release liner to promote adhesion to the bottom substrate.
  6. Allow the EPDM membrane to fall freely onto the Seam Tape. Remove release liner at a 45º angle.
  7. Immediately roll the splice with a 2” (5.08 cm) wide silicone roller. Roll perpendicular to splice edge.
