Description
PRINTABLE RELEASE COAT FOR DOUBLE CORONA TREATED POLYOLEPHYNIC SOLVENT RUBBER ADHESIVE TAPES
RELEASE ST8 DRY is a powder compound based on synthetic resins, easily soluble in an aromatic solvent like toluene.
Application
RELEASE ST8 DRY is designed to replace the normal release coat (Release PP 25S or RELEASE K100D) in the production of BOPP 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
The best performance has been obtained with 0.5-0.6 g (dry)/sqm coating weight. Concentration shall be adjusted accordingly with the coating system. For standard applications, we suggest diluting with toluene at 12% and coating 4-5 g (wet)/sqm on flame treated BOPP film (minimum 42 dynes/cm).
It is important to note that, being RELEASE ST8 DRY a heterogeneous product, the content of one single bag should be completely used up, without splitting its content into different batches.
Application temperature of the solution shall preferably be between 30 and 40°C, and never below 20°C. Stir well before use. Coating must be perfectly dry (less than 0.6 g/sqm of residual solvent).
Solvent rubber adhesives can be coated directly on line on the other treated side of the BOPP film.
Packaging
The product is packed in fibre drums, containing 5 kg PE bags.
Storing
Use within 24 months from production date (unopened and in the original packaging).
Notes
Ichemco can supply a wide range of suitable polyamide inks (COLOR INK PP PAM + ADD and ECO INK PAM RU series - one component inks, ready to use). See our web site (www.ichemco.it/inks) for a full list. The printing machine must use specific settings (we suggest to contact SIAT SPA), e.g. the larger cylinder (opposite to the printing rolls) must be heated at 40-50°C. Before printing, brush off the surface with a felt to activate the surface by friction.
