Abstract:
A fibrous, nonwoven electrically conductive mat particularly suited for use in making a glass fiber reinforced product, said mat containing 10 to about 20 weight percent resin binder on a dry mat basis and a majority of glass fibers, a majority of the glass fibers being electrically conductive by having a conductive metallic coating on at least a part of the surface of the glass fibers, said electrically conductive glass fibers comprising 50-90 weight percent of the dry mat, said fibers bonded together with an elastic or stretchable resin binder, said resin binder containing predominantly acrylate containing crosslinked polymer chains including repeating units derived from itaconic acid and an acrylate, said mat having a surface resistivity of less than 500,000 ohms/Sq.
