Processing

Mesh
All commercially available polyester mesh can be used.
Stencils
All commercially available stencils can be used.

Curing
Bonding of the ink system depends on temperature, used hardener and layer thickness. To reach maximum resistance, a minimum temperature (see point „hardener“) must be guaranteed over a duration of 5 to 10 days. By increasing the temperature the ink film cures faster and an earlier and even better chemical resistance can be achieved.

Curing times

  • Series 600-HDA- 7 days (at minimum temperature)
  • Series 600-HDS -10 days (at minimum temperature)
  • Series 600-HDI- 5-7 days (at minimum temperature)
  • Forced drying- 30 minutes at 120°C

It is important to ensure, that temperatures do not fall below within the first 48 hours. An increased moisture supply during drying time can permanently damage the ink film

Overprintability
The ink film can be overprinted with a suitable ink system, preferably before complete curing of the ink.

Further Processing

  • Embossing
  • Punching
  • Bending
  • Cutting *

* After preliminary test

Cleaning

Intermediate cleaning of stencils and squeegees should be done in a timely manner with Series 600-BRS. Final cleaning can be done with Series 600-URS.

Productivity

Depending on the color shade, a productivity of 45-65 m2/kg is to be expected with press-ready ink and use of a mesh 120.34.
