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.

Product Features

  • Fast and easy-to-use permanent bonding method provides high strength and long-term durability
  • Virtually invisible fastening keeps surfaces smooth
  • Can replace mechanical fasteners (rivets, welds, screws) or liquid adhesives
  • Dark gray, 0.045 in (1.1 mm), general purpose adhesive with firm foam has added feature of high temperature resistance
  • Eliminate drilling, grinding, refinishing, screwing, welding and associated clean-up
  • Creates a permanent seal against water, moisture and more
  • Pressure sensitive adhesive bonds on contact to provide immediate handling strength
  • Allows the use of thinner, lighter weight and dissimilar materials
