Bostik web adhesive is a hot melt adhesive in open-net form that handles like a fabric. This material will fuse to cottons, synthetics, leather and paper. The web adhesive is white in color and weighs approx. 20 grams per square yard. It will soften at approx. 268°F to form a micro-thin layer of adhesive film. This can be easily done with a tacking iron.
