Product information

tesa® FUSE 45012

Heat-Reactive Self-Adhesive Bonding Tape

Product description

tesa® FUSE 45012 is a heat-reactive self-adhesive bonding tape consisting of a specialty adhesive covered with a clear filmic liner. The product has been designed for bonding metal parts before powder coating. Fast, clean and flexible during assembly, it withstands the typical powder coating process including chemical pretreatments and temperatures up to 220°C. In the oven, it builds a strength of up to 300 N/cm² remaining elastic enough to compensate for thermal elongation.
tesa® FUSE combines process advantages of tape with semi-structural bonding power. It enables metal fabricators to use tape for bonding before powder coating and offers advantages compared to technologies like e.g. welding, liquid adhesives or regular bonding tapes:
  • Invisible bonding technology, excellent surface quality
  • Freedom to combine different metal types
  • Efficient assembly and material workflow

Main applications

  • Durable, semi-structural metal bonding for e.g. metal trims, profiles, frames, panels or attachment parts
  • Exclusively for metal modules, that will be powder coated after bonding
  • Suitable for aluminum, steel or a combination of both
