Abstract: Heat-activated adhesive tape has a backing comprising 88-92% acrylic polymer containing: 35-45% of a first alkyl acrylate monomer with alkyl groups containing 4 to 12 carbon atoms, 30-40% of a second alkyl acrylate monomer with alkyl groups containing 4 to 12 carbon atoms, 6-10% a first monoethylenically unsaturated polar copolymerizable monomer, 1-2% a second monoethylenically unsaturated polar copolymerizable monomer, 0.3-0.5% photoinitiator, 1-2% filler, 0.05-0.07% crosslinker/chain extender, and 8-12% hollow glass microspheres; and heat-activated adhesive layer on at least one side. A pressure-sensitive adhesive may be on the other side.

Abstract: Pressure-sensitive adhesive tape has a backing comprising 88-92% acrylic polymer containing: 35-45% of a first alkyl acrylate monomer wherein the alkyl groups contain 4 to 12 carbon atoms, 30-40% of a second alkyl acrylate monomer wherein the alkyl groups contain 4 to 12 carbon atoms, 6-10% a first monoethylenically unsaturated polar copolymerizable monomer, 1-2% a second monoethylenically unsaturated polar copolymerizable monomer, 0.3-0.5% photoinitiator, 1-2% filler, 0.05-0.07% crosslinker/chain extender, and 8-12% hollow glass microspheres dispersed evenly in the polymer; and a pressure-sensitive adhesive layer on at least one side of the backing.

Abstract: A medical device for the transdermal delivery of an appetite suppressant drug wherein said device comprises a silicone-coated release layer, a coating containing a mixture of a pressure-sensitive adhesive, an appetite suppressant drug, a permeation enhancer and a PH control additive wherein said coated release layer is laminated to a carrier layer.

Abstract: A hand-tearable masking tape comprising a tearable backing and an adherable face which permits the tape to be readily removable from a surface to which the tape is applied, the backing comprising a plastic film containing sufficient filler to bring the Elmendorf tear strength of the film to between about 150 and 300 gms.
