<p>A release surface for use in diaper tape assemblies comprises a cured release coating of a reactive silicone system comprising at least 15% by weight of a reactive polydialkyl siloxane, at least 40% by weight of a defined reactive silicone high adhesion agent and a silicone crosslinking agent. Cure occurs in the presence of Group VIII metal catalyst, and the cured release coating has a coefficient of friction of less than about 0.7 lb/2 inch (62.6 g/cm) and a release greater than 50 g/in (19.7 g/cm). A diaper tape assembly comprises a release tape (12) and a diaper fastening tape (14) adhesively bonded into a Y-shaped configuration; each tape (12, 14) comprises a substrate (20, 26) coated on one face with a pressure sensitive adhesive (18, 22) and on the opposite face with the release coating (16, 24). <IMAGE></p> |
