ARclean® W-5029

Product Overview

ARclean® W-5029 is a 2 mil (51 μm) clear polyester release liner with a tight release, thermally cured, solventless silicone coating on one side and is printable on the opposite side. ARclean® W-5029 is formulated and designed to have low extractables.

Product Applications

Typical use for this product is as a support and protection film for non-silicone pressure-sensitive adhesives (PSAs) and cast materials requiring a tight release. ARclean® W-5029 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.

Features and Benefits

  • Low extractable silicone surface prevents silicone contamination

  • Tight release from PSAs, including acrylic, rubber, hot melt, hydrocolloid, and others

  • Tight 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 coatings

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

  • Adhesives Research 5000 series silicone release liners meet the requirement of USP 661.1, Packaging Materials of Construction for Pharmaceutical Use

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

  • Clean room application compatible

  • Retains adhesion and backside printability without silicone contamination
