ARclean® W-4012

Product Overview

ARclean® W-4012 is a 3 mil (76 μm) clear polyester release liner with an easy release, thermally-cured, solventless silicone coating on one side and is printable on the opposite side. ARclean® W-4012 is formulated and designed to have low extractables

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 release. ARclean® W-4012 is ideally suited for applications including specialty die-cut adhesives and labels, engineered tapes, skin- friendly adhesives, medical devices, and electronics.

Features and Benefits

  • Low extractable silicone surface prevents silicone contamination

  • Easy release from PSAs, including acrylic, rubber, hot melt, hydrocolloids, and others

  • Easy release from cast materials, including elastomers, foams, ceramics, and dispersions

  • Narrow consistent release profile preventing adhesive confusion

  • Stable release properties, no “lock-up,” and consistent release force over time

  • Green, environmentally friendly, solvent-free coating

  • Excellent thermal stability, aging resistance, and anchorage to polyester base film

  • Suitable for indirect skin and food contact, US FDA Drug Master File (21 CFR)

  • Retains adhesion and backside printability without silicone contamination
