- 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.
