Product Description

This 25.5" x 328' MHA (Multi-Heat Adhesive) is an economical, heat activated mounting adhesive with a moisture-stable release liner. MHA's initial tack is very low, making it easy to apply. This feature allows most prints to be repositioned on MHA pre-coated boards without damage. Once satisfied with the alignment, process the graphic and board through a heated roll laminator (185 F - 220 F / 85 C - 140 C) for a permanent bond. The 25.5" x 328' MHA's forgiving nature has made it a popular product with photographers for thinner "bond papers" such as graphic renderings, drawings, blueprints, color copies, courtroom displays, etc. Although MHA's initial tack is low, the bond insitantly becomes permanent once processed through a heated roll laminator. It is therefor suitable for flexible and rollable substrates such as expanded PVC graphic materials (e.g. Sintra). Use MHA in conjunction with MediaShiled overlaminate and MHL overlaminating films. Product number MHA25328.

Item Specifications

  • When Mounting thicker prints/ output it is recommended to increase the temperature of the heated laminator rollers to a minimum of 200 F while reducing laminator feed speed to ensure sufficient heat permeates through the print image, board and (optional) overlaminating film to activate the MHA adhesive
  • We do not recommend using the laminator's idler bar when applying MHA
  • MHA only works on heated roller laminators, not hot-shoe style laminators

Technical Data

MHA (Multi-Heat Adhesive) is a heat activated, solvent acrylic mounting adhesive that is protected by a moisture stable bleached Kraft diff erential release paper coated on both sides with siliconized PE. This carrier-free adhesive off ers a superior bond to fl exible and rollable substrates, such as Expanded PVC (e.g. Sintra™), and is an excellent solution when paired with Drytac’s MediaShield and MHL laminates. It has a low initial tack before heat is applied that allows it to be re-positioned, and it can be heated multiple times to activate the adhesive. After activation is complete, a strong bond is formed. MHA can be die cut and is considered self-trimming since it is carrier-free.

Typical Applications
  • Recommended for mounting of canvas, where the back of the canvas and the substrate to be used are both coated with MHA and married together for a very strong bond.
  • Ideal for mounting images on MDF to create plaques; can be trimmed and foiled without the images lifting.
  • Suitable for manufacturing processes to create a strong bond between two substrates.
