How to Seal Zippertubing Extruded Tracks
How to Seal Zippertubing Extruded Tracks: We offer advice as to how to seal Zippertubing Zip-On and Zip-Shield products.
These instructions will work with all* Zippertubing® extruded tracks (*except type FEP). All Zippertubing® products that utilize extruded closure tracks can be permanently sealed after closure using the following method. Under normal circumstances a properly closed Zippertubing® track does not require post closure sealing. However, in some applications where an environmental or tamper proof seal is desire or extreme abuse is anticipated, the post sealing process can ensure that the track does not re-open inadvertently.
ZT-Tape
This method involves placing a 1-inch wide strip of Zippertubing’s ZT-Tape down the center of the inter-locking track split line after the track has been closed. Before installing the tape, make sure that the track and sleeving is clean and free of any debris or moisture; wipe down with isopropyl alcohol or a mild cleaning agent if necessary. Applying slight pressure to the tape after installation will provide the best adhesive bond strength to the track surface below.
ZT-Tape is a UL-510 recognized, fire retardant, Polyurethane film tape with an Acrylic adhesive backing. The adhesive is compatible with both PVC and PFR track materials and is easily applied. The tape sealing method provides additional closure strength, improves environmental tightness and is an environmentally friendly process.
CAUTION: The ZT-Tape is highly elastic and must be applied to the track in a relaxed condition. Stretching the tape during installation can result in disbonding of the film from the adhesive if the assembly is stored or shipped in a coiled or tightly bent condition.
