Films with release coatings are in strong demand for a wide range of applications from window films to flexible displays. In searching for replacements for tin-based catalysts used to cure liquid silicone coatings applied to film substrates such as PET, we aim to preserve the essential characteristics of the "Sn"-cured coatings. These include extractables, the expected peel release values (PRV) of calibrated test tapes, expected PRVs of laminates with selected adhesive(s), and the retention of such properties for twelve months or more. Measurements of peel release values highlight the difficulty of defining the performance of a release surface.
