How to Choose Acid-Free ATG Tape for Framing, Mounting and Assembly

by Fernando Gonzalez on Sep 15, 2026

Adhesive transfer tape applies a controlled film of pressure-sensitive adhesive without a conventional tape backing. It is useful for clean, fast mounting and assembly work—but the refill must match the material, width, core and dispenser.

This guide focuses on ATG-7502 acid-free adhesive transfer tape and explains how to select the right configuration for framing, paper projects, displays and light assembly.

What makes ATG-7502 different?

ATG-7502 is a reverse-wound, 2.0 mil transfer tape with a glass-stabilized, solvent-based acrylic adhesive on a gold paper release liner. It is acid neutral, making it a useful option when an acid-free adhesive is required for paper-based projects.

Each roll is 36 yards long on a 1-inch plastic core. The tape is offered in nominal 1/4-, 3/8-, 1/2- and 3/4-inch widths, with multipacks and full-case quantities that vary by width.

Common ATG-7502 applications

  • Picture framing and paper mounting
  • Scrapbooking and stationery projects
  • Nameplate and display mounting
  • Envelope sealing
  • Paper web splicing
  • Prototype packaging
  • General holding and product assembly

The adhesive is designed for paper, most plastic films and metal foils. Always test the tape on the actual materials before committing to a production run.

How to choose the tape width

Match the tape width to both the bond area and the dispenser. A narrow 1/4-inch roll works well for slim borders and detailed paper work. Wider 1/2- or 3/4-inch rolls cover more surface area for broader mounting and assembly tasks. The listed inch sizes are nominal; for example, a nominal 1/2-inch tape is approximately 12 mm.

After choosing the width, select a pack quantity that reflects your expected usage. Smaller multipacks are practical for testing and occasional work. Full cases can reduce handling for repeat production or wholesale needs.

Dispenser compatibility matters

ATG refills are reverse wound and designed to run through compatible applicators. ATG-7502 uses a 1-inch plastic core and works with compatible dispensers including the ATG-50 adhesive transfer tape dispenser.

The ATG-50 accepts 1/4-, 3/8-, 1/2- and 3/4-inch reverse-wound refills, but it does not accept 60-yard rolls. ATG-7502 rolls are 36 yards long. If you are matching a different dispenser, confirm its supported width, core and maximum roll length before ordering.

ATG-7502 vs. ATG-7501 and ATG-7502X

  • ATG-7502: 2.0 mil, acid-free acrylic adhesive for general mounting, framing and paper projects; all rolls are 36 yards.
  • ATG-7501: a thinner 1.6 mil acrylic option offered in selected 36- and 60-yard configurations.
  • ATG-7502X: a 2.0 mil high-tack option for applications requiring stronger initial grab, with selected 36- and 60-yard rolls.

Acid-free status, initial tack and dispenser compatibility are separate requirements. Choose the product that meets all three rather than selecting on thickness alone.

Application tips

  1. Clean the bonding surfaces and remove dust, oil or loose fibers.
  2. Install the refill according to the dispenser instructions.
  3. Apply steady pressure while moving the applicator across the first surface.
  4. Burnish the applied adhesive before removing or folding away the liner path.
  5. Join the second surface carefully, because repositioning may be limited.
  6. Test bond performance under the temperature and handling conditions of the finished project.
