Kiwo 1:20 Stencil Remover - Gallon
Stencil Remover 1:20 concentrate is a highly concentrated liquid emulsion remover for de-coating polymer-based direct emulsions and capillary films. STENCIL REMOVER 1:20 concentrate provides maximum efficiency when diluted with 20 parts water but may be diluted with up to 50 parts water depending on the type of emulsion and desired effectiveness. STENCIL REMOVER 1:20 concentrate does not crystallize when drying and is suitable for use in automatic reclaiming equipment.
- Apply the diluted Stencil Remover 1:20 concentrate solution with a soft, clean brush evenly on both sides of the screen after the screen has been carefully cleaned of ink residue.
- Rub the screen gently with a brush to dissolve the emulsion.
- After approximately 2 minutes, rinse thoroughly with a strong water spray. A high-pressure water spray (1000 - 2000 psi, 40 - 60 bar) may be required for highly water resistant emulsions. Prolonged reaction time may result in reverse effects and does not help in the de-coating process. Rather, rinse the screen and reapply fresh STENCIL REMOVER 1:20 concentrate.
Ensure that the STENCIL REMOVER 1:20 concentrate solution does not dry on the screen. This can lead to a hardening of the emulsion and the resulting emulsion residues will be extremely difficult to remove. For automatic equipment a dwell time of 60 -120 seconds after applying the de-coating solution is sufficient. If not all emulsion is removed, a second reclaiming cycle should be used to completely remove the emulsion.
