New Pressure Sensitive Adhesive for High Temperature Hook and Loop Tape Fasteners

Posted on 6/18/2020 9:46:08 AM By ASC

Once known mainly for replacing buckles as quick and easy ways to fasten sports footwear and hikers’ backpacks, hook and loop tape systems have risen to far higher levels over the years. They’ve found their place in the aeronautics, automotive and other industries, taking over the roles of a number of other mechanical fasteners like zippers, snaps, hooks and screws, and they have also swapped from using stitches, to utilizing adhesives for attachment to multiple substrates.

Other developments have given rise to specialist hook and loop tapes, such as 3M’s woven nylon high temperature hook fastener designed for signage and display, medical brace closures and for fitting seat backs and cushions in the aerospace and specialty vehicle assemblies. The company reports that this adhesive-backed hook and loop tape duo can withstand temperatures of up to 185°F, is suitable for indoor and outdoor use, and can be separated and effectively refastened up to 5,000 times without the fastening strength being compromised.

According to the company, a general purpose acrylic-based pressure sensitive adhesive was chosen to back the high temperature tape because of the adhesive’s moisture and heat resistance, shear strength and UV stability and for its ability to bond well with both low energy substrates like polystyrene, polycarbonate, acrylic and nylon, as well as those with high to medium surface energy such as clean, dry metals.
