Seven blue metal strips with hole-punched ends, labeled with tesa and FUSE 45012, are laid flat on a speckled gray surface. Two strips have red ends.

First Bond, Then Powder - Problem Solved

Technologies

tesa® FUSE 45012 is a ground-breaking bonding solution enabling metal fabricators to bond metal modules with heat-reactive self-adhesive tape before powder coating.

Introducing tesa® FUSE 45012:

  • Heat-reactive self-adhesive tape in roll format
  • Bonds metal parts before powder coating
  • Cures to final strength in the powder coating oven
  • Features semi-structural bonding performance

Typical Applications

tesa® FUSE 45012 can be used to bond metal parts, even dissimilar materials like steel and aluminium. It provides a firm and durable bond for applications such as stiffeners, frames, cover plates, or attachment parts.

Several metal components, including rectangular boxes and curved bars, are hanging from hooks attached to a metal frame in what appears to be a workshop or assembly area with a concrete floor and white brick walls. (This text has been generated by AI)
A stack of metallic panels and a separate metal strip lying on a flat surface. The panels appear reflective and are partially wrapped at the edges with tesa tape. The metal strip rests diagonally across the panels. The background includes wooden elements. (This text has been generated by AI)
Stacks of large metal panels are leaning against a table in a warehouse. Nearby, there are boxes on a cart and other materials, including rolls of tesa tape. The scene is well-lit, with a concrete floor and industrial surroundings. (This text has been generated by AI)
A metal tray with a shallow edge is secured using tesa tape on a wooden pallet. The pallet is situated on a paved outdoor surface. Another reflective metal sheet or tray, also secured with tesa tape, is partially visible in the background on the pallet. (This text has been generated by AI)
A series of rectangular frames hang from a metal rod in an industrial setting. The frames are painted dark gray and are suspended in a row against a background of white brick walls and a concrete floor, all secured using tesa tape. (This text has been generated by AI)

Working Principle

A person wearing a dark short-sleeve shirt and blue gloves is assembling or disassembling a metal frame and panel. They are holding a rectangular metal sheet above a rectangular metal frame on a green grid mat, using tesa tape for secure positioning. (This text has been generated by AI)

01Metal Bonding

tesa® FUSE 45012 can be applied like a self-adhesive tape during assembling. It saves time due to a fast, clean, and simple process.

 
Two black, square metal frames hang from a rail inside an industrial-looking space with a white brick wall. The frames are suspended at different angles using tesa tape, suggesting they are part of a manufacturing process. (This text has been generated by AI)

02Powder Coating

tesa® FUSE 45012 withstands typical chemical pretreatments, the cleaning and drying process, as well as very high oven temperatures. During the baking process, tesa® FUSE 45012 cures to final strength.

03Outstanding Performance

After powder coating, tesa® FUSE 45012 provides very high bonding strength and temperature resistance. It remains elastic enough to compensate for thermal elongation of different metal types.
