A thin adhesive film which acts like a double-sided tape with no substrate, just the adhesive alone. It is a dry mount adhesive recommended for mounting silk on mats, and for mounting prints and photographs without the need for a dry mount press. Acid free (pH 7), passed the photo activity test (PAT), and will not dry out or discolor with age.
As the roll is unwound, the adhesive side is exposed (pictured). The adhesive side is attached, burnished and trimmed. The reverse side is exposed by stripping off the release paper, attaching it and re-burnishing to make full contact. Can be reversed by jelling the adhesive with acetone or xylene and then removed by rubbing.
