4936 VHB™ Tape
25 mil Gray Conformable Acrylic Foam Tape
3M™ VHB™ Tape is a 25 mil, double sided, 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 polyethylene film liner.
