3M 4926

3M VHB™ 15mil Gray Acrylic Foam

3M 4926 is a 15 mil, VHB™ double-coated, conformable acrylic foam. 4926 is the main product when conformability is necessary. 4926 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 4926 can replace rivets, spot welds, liquid adhesives or other permanent fasteners.
