Product Overview

ARclean® W-5049 is a 2 mil (51 μm) clear polyester release liner with an easy-medium release, thermally cured, solventless silicone coating on one side.

Product Applications

The typical use for this product is as a support and protection film for non-silicone pressure-sensitive adhesives (PSAs) and cast materials requiring easy-medium release. ARclean® W-5049 is ideally suited for applications in medical and electronics where a clean and consistent removal of the release liner from the adhesive or coated material is required.
