Compac #110 FSK insulation tape features an aggressive, all-weather acrylic adhesive that bonds tightly and permanently when smoothed down on the insulation facing surface. All Weather (AW) adhesive technology permits service temperatures of 0ºF to 150ºF (-18ºC to 66ºC), and an application range of 10ºF to 120ºF (-12ºC to 49ºC). It is primarily used for seam sealing and patching of FSK-faced duct wrap insulation.
