KOOLGLIDE tapes have adhesive bands on the edges and center of the tape.
When the KOOLGLIDE tool is activated, the resulting melting pattern matches the tape adhesive.
The KOOLGLIDE tool and tape system is designed to allow for misalignment of the tool and tape (not to exceed ½” off) and still make an excellent quality seam. This is accomplished by placing extra adhesive on the edges and the center. Therefore, even when the tool is perfectly aligned some adhesive will be left un-melted.
