Waterproofing tapes
Formable EPDM flashing tape for pipe penetrations, corners and drains. The standard type has a butyl adhesive backing and no aluminium mesh. Use with a compatible primer and hand roller.
Shape the EPDM face around corners, penetrations and three-dimensional details for supplementary waterproofing, flashing and local repairs.
A butyl adhesive layer and peel-off release film support placement at the detail. Use a compatible primer and consolidate contact with a hand pressure roller.
The EPDM face gradually self-vulcanises at ambient temperature after installation. Confirm the timing and installation conditions for the selected system.

WP-TAP-000003 combines a formable EPDM face with a butyl adhesive backing and release film. The standard type has no aluminium mesh reinforcement. Shape it around pipe penetrations, drains, internal and external corners, or transitions between horizontal and vertical surfaces. You can also discuss local repairs in compatible waterproofing systems.
The EPDM face self-vulcanises over time at ambient temperature. Confirm timing for the intended site conditions before scheduling subsequent work. Check the substrate, surface coating and primer, including compatibility with related EPDM membranes and suitability for movement, long-term exposure or immersion.
The standard black roll is 20 m × 200 mm × 1.5 mm. The thickness and its ±0.1 mm tolerance exclude the release film. Width tolerance is ±2 mm; minimum roll length is 20 m. Standard packing is 4 rolls per carton.
Agree primer coverage and drying time, overlaps, terminations and rolling requirements for the detail before installation.
The TDS reports these JC/T 942-2022 results for the 20 m × 200 mm × 1.5 mm specimen, with thickness excluding release film. These measured results are not guaranteed minimums and do not establish performance for custom sizes.

Unopened shelf life is 12 months under these conditions. Confirm the start date for the supplied batch and how long you can use it after opening. Ask for written warranty terms with your order.
EPDM self-vulcanising flashing tape: technical data sheet
WP-TAP-000003: standard tape without aluminium mesh, 20 m × 200 mm × 1.5 mm excluding release film. Includes application guidance and JC/T 942-2022 results, not guaranteed minimum values or application and service temperature limits.
Yes. Apply a compatible primer, form and bond the tape to the detail, then press it with a hand roller. Confirm surface preparation, overlaps and terminations for the selected system.
The EPDM face self-vulcanises at ambient temperature. Share your expected site conditions and work schedule so we can confirm the timing before you plan subsequent work.
No. Heat resistance at 100 °C, flexibility at −40 °C and tack at 5 °C are separate laboratory tests. Ask us to review installation temperatures, long-term exposure and any immersion requirement for your detail.
Unopened material has a stated shelf life of 12 months at room temperature under the specified storage conditions. Ask when the shelf life starts and how long you can use the material after opening. This period does not define installed service life or warranty coverage.
