<p>SILOXANE-PVA COATING COMPOSITIONS Astract Homogeneous compositions containing certain liquid siiicone resins, a high-hydroxyl polydimethylsiloxane, poly(vinyl alcohol) and water are useful for coating a substrate to provide an adhesive-releasing coating on the substrate. The compositions are particularly useful as a tape backsize having moderate release and substantially no adverse effect on the adhesiveness of the tape.</p> |
