PROPERTIES & USES:
- Lower tendency of binder film to coagulate and dry-up on screens, due to heating
up of
the paste in hot climate.
- Disperses pigment residues which can agglomerate in the screen.
- Re-disperses un-cured binder films that dried up in the screen.
- Keeps screen clean and open during long runs of printing.
- Screen cleaning operation, after printing or in between color way changes,
becomes
much easier.

Add to the printing paste after all the thickener is incorporated, before addition of the binder and the pigments.
-
Usage level should be 5-10 g/kg.
