3M 4936
3M VHB™ 25mil Gray Conformable Acrylic Foam

General Information
3M 4936 is a 25 mil, VHB™, double-coated, conformable acrylic foam. 4936 is the main product when conformability is necessary. 4936 utilizes multi-purpose acrylic adhesive on both sides of a conformable foam. It has excellent adhesion to a broad range of high and medium surface energy substrates including metals, glass and a wide variety of plastics and plasticized vinyl. In many cases 4936 can replace rivets, spot welds, liquid adhesives or other permanent fasteners. 4936F is the same product on a 5 mil clear polyehtylene film liner.
