3M™ VHB™ Tape 4611 is a 0.045 inch (1.1 mm) thick dark gray double-sided acrylic foam tape with PE film liner. The general purpose acrylic adhesive on both sides bonds to a broad range of high surface energy substrates including metals, glass and easier to bond paints and plastics. The firm foam provides high foam strength and has high temperature resistance. 3M™ VHB™ Tape 4611 is part of the 4611 tape family. Each product in this family has general purpose acrylic adhesive but varies in thickness.
