Abstract: A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls.

Abstract: A water resistant, flexible, dermal adhesive product for conformable topical application to human skin, the dermal adhesive product comprising a backing sheet having an adhesive for removably adhering the sheet to the skin, wherein the adhesive is a highly crosslinked pressure sensitive adhesive composition comprising the polymerization reaction product of about 75% to about 95% of a mixture of at least two alkyl acrylate or methacrylate esters, about 1% to about 10% ethylenically unsaturated carboxylic acid, and about 10% to about 20% vinyl lactam, by dry weight of solids, preferably about 80% to about 90% of a mixture of at least two alkyl acrylate or methacrylate esters, about 2% to about 5% ethylenically unsaturated carboxylic acid, and about 10% to about 20% vinyl lactam, by dry weight of solids.
