ARclear® 44110

Product Overview

ARclear® 44110 is an optically clear moisture barrier pressure-sensitive adhesive (PSA) transfer tape.

Product Applications

The typical use for this product is as a moisture barrier adhesive in various electronics and optical device applications. It is suitable for use in combination with high-barrier films such as inorganically coated plastics. It exhibits good adhesion to a variety of substrates. The adhesive is uncrosslinked and, as such, is not recommended for high-shear and high-temperature applications.

Features and Benefits

  • High optical transmission, high clarity, low haze, and non-yellowing
  • Optically clear transfer film with good moisture barrier properties
  • Hydrophobic adhesive with excellent thermooxidative and UV stability
  • Easy, mess-free processing and bonding
