Applications & Uses

Product Applications

• Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
• Depending on the construction of the equipment, a continuous heating above processing temperature can cause decomposition of the adhesive.
• Tank melters should use protective gases with < 5 ppm humidity, only. Rakoll® 2021 is moisture sensitive, therefore container must be kept closed.
• After drying the bond is effected by activation in the 3D process. Bonding time depends on thermal conductivity of the substrates.
• Pressing time depends on temperature, pressure and substrates. Bonding and pressing times must be determined by preliminary tests.
• Water for fresh adhesive, when film is dried use Korasolv® PU or Isa™Verdünner 220.
