3M™ VHB™ Tape 4941F
Gray Conformable Acrylic Foam Tape - Poly Liner
3M™ VHB™ Tape 4941F is a 45 mil, double sided adhesive foam. It is one of two 3M VHB; core go-to items. 4941F is the main product when conformability is necessary. 3M's other go-to item when internal strength is more important than conformability is 4950. The 4941F family 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 4941F can replace rivets, spot welds, liquid adhesives or other permanent fasteners. This product is available with a paper liner as 4941.
