Abstract

A novel approach of incorporating scrim in an adhesive matrix is used to maintain differential release properties. The combination of adhesive and scrim provides the necessary release differential for low surface energy adhesives such as silicone adhesives. The examples described show 50 to 75% improvement over standard constructions.

Silicone Adhesive Transfer Tape

                    A novel approach of incorporating scrim in an adhesive matrix is used to maintain differential release properties.  The combination of adhesive and scrim provides the necessary release differential for low surface energy adhesives such as silicone adhesives.  The examples described show 50 to 75% improvement over standard constructions.

Silicone Adhesive Transfer Tape

                    Silicone based, such as fluorosilicone based, low surface energy (LSE) liners are widely used as release liners with acrylic, rubber-based and other types of adhesive tapes since they exhibit good differential release properties.  However, the same silicone or other LSE liners are not very effective as release liners for silicone adhesive tapes since the necessary differential release no longer occurs.

                    To overcome this difficulty, a novel approach of incorporating a single layer or multiple layers of scrim, such as woven scrim, non-woven scrim, conductive scrim, non- conductive scrim, or combination of particles and scrim, in the adhesive matrix is employed.  The combination of adhesive and scrim provides the necessary release differential to be effective against low surface energy adhesives such as silicone adhesives.   The employment of the scrim not only assists in the release of the LSE liner from a silicone adhesive-liner interface but also provides dimensional stability to the silicone adhesive when...
