Updated . Edited by: Ilyass Ben Hakim.

Where to buy

Hardware stores carry small consumer rolls. Industrial suppliers and electronics distributors sell full width rolls by part number.

Professional insight

Fabricators choose VHB by substrate surface energy first. Thickness comes next, to fill gaps.

  • Powder coat and plastics often need the 5952 family.
  • Clear 4910 suits glass and clear acrylic joints.
  • Full bond strength builds over about 72 hours.
  • Press hard: pressure matters more than time held.
