Abstract
Pressure sensitive adhesive having favorable adhesive, shear, liquid permeability, and release characteristics. The adhesive is a crosslinked polymerization product of a methyl/phenyl siloxane gum, dimethyl siloxane gum and a polysiloxane resin. The resulting product provides suitable adhesion to a large number of surfaces and has particular utility as an adhesive between plastic film and human skin, especially for use with transdermal therapeutic devices. The adhesive characteristic mitigates damage to underlying surfaces such as human skin tissue during adhesive removal.
