Hot-melt adhesives

Everad makes a distinction between heat-activated hot-melt adhesives and pressure-sensitive adhesives.

Joints with heat-activated adhesives must be bonded within a specific time frame, known as the “open time”. PSAs (pressure-sensitive adhesives) on the other hand remain permanently adhesive. After coating, the adhesive film must be covered with a protective layer.

Polyurethane hot-melt adhesives reticulating with humidity, they offer high heat resistance and tensile strength once the reaction is complete.

To manufacture hot-melt adhesives, raw materials such as polymers, resins, plasticisers and additives are blended at high temperature in mixers. The resins and plasticisers are worked into the polymer.

Manual application

Automatic application


  • Solvent-free
  • No energy required for drying
  • Pre-coating possible
  • Adhesion to a wide variety of substrates thanks to the large choice of raw materials
  • Single spread
  • High initial setting and final cohesion
  • Possibility of bonding under pressure
  • Flexible joint
  • Versions without residual tack to avoid annoying noise
  • Light-coloured formulations therefore invisible under light-coloured or fine textiles
  • Various application processes possible by spraying, beads, dots, slot dies
  • High resistance to water and humidity
  • High temperature resistance
  • FR (flame retardant) versions
  • Workpieces can be handled immediately
  • Pack-free system for simple, quick and direct use in melting machines, saving time and reducing waste
  • High yield

Everad HCM 5550 is a particular adhesive that is among the world’s most modern technologies. This adhesive is applied in powder form and then heated to 65°C. The coated substrate can then be rolled up as the adhesive is not tacky at that point.

In the second stage, the adhesive will be reactivated at a temperature of 120–140°C. The reaction that occurs at this temperature will reticulate the adhesive and give it its final strength with very high temperature stability properties.



  • Bonding pieces of foam together and to other substrates for the manufacture of mattresses, padded furniture and technical foam
  • Lining of various substrates with non-woven textiles
  • Wood bonding for lamination or edge banding
  • Packaging
