COLPLY EF Adhesive is a high performance, single-component polymeric adhesive for use with SBS-modified bitumen membrane systems. Due to its polymer composition, once cured, COLPLY EF Adhesive provides an additional layer of elastomeric waterproofing protection beneath or between membrane plies. COLPLY EF (environmentally friendly) Adhesive is unique in that it is a solvent-free and ultra-low VOC material allowing for application flexibility on job sites where exposure to VOC’s or odor may be a concern.
