RELEASE ST4 M is a compound in solvent solution, designed to replace the normal Release coat (Release PP 25S or RELEASE K100D) in the production of PP adhesive packaging tapes, in order to achieve tapes which will be printable with a single-step printing machine (similar to PVC tapes, without using primer and release) using only suitable inks (see notes below).

- Handling
RELEASE ST4 M must be heated and well stirred before use, until it becomes perfectly liquid. Product temperature should never go below 20°C (preferably between 30-40°C).
Suggested dilution: 1 pp with 15 pp of a blend of toluene and isopropyl alcohol (70 : 30).
Suggested coating weight: 4-6 g/sqm wet on untreated BOPP film. Coating must be perfectly dried (less than 0.6% of residual solvents). Hot-melt or solvent rubber adhesives can be coated directly on line on the other treated side of the BOPP film.
