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.

Working Principle

Metal Bonding

tesa® FUSE 45012 Metal Bonding

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.


tesa® FUSE 45012 Powder Coating

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. 

Your Advantages

tesa® FUSE 45012 has been designed to combine the advantages of tape with the strength of an adhesive. It allows metal fabricators to improve their processes and implement new ideas. 

  • Invisible Bond - Perfect surface finish
  • Design Freedom – Build modules from different metal types
  • Efficient Process – Finish module assembly before powder coating
  • Higher Performance - Significantly higher bonding strength and temperature resistance than regular tape
  • Time-saving – No surface finish or rework like grinding needed
  • Increased productivity - Immediate handling, no curing time needed
