摘要:
Pressure sensitive adhesives for use primarily in medical applications are disclosed. The pressure sensitive adhesives are urethane elastomeric adhesives that include a polyurethane polymer and a compatible tackifier and/or compatible plasticizer to achieve an adhesive having a predetermined compliance. The result is a pressure sensitive adhesive for application to skin that can eventually be removed with very little trauma to the skin and with a low pain rating, but which still exhibits very good peel strength when used to construct an article in which the adhesive is adhered to human skin.
摘要:
A pressure sensitive adhesive includes a substantially continuous polymer phase having pressure sensitive adhesive properties, and a plurality of pores arranged within the substantially continuous polymer phase and disposed to permit fluid to pass from a first side through at least a portion of the plurality of pores to a second side. The plurality of pores is substantially resistant to cold flow. A method of forming a porous pressure sensitive adhesive tape includes providing a solution for forming an adhesive having pressure sensitive adhesive properties, the solution including a pore forming material, casting a film comprising the solution, laminating a liner on the film, and exposing the adhesive to an energy source to form pores in the adhesive and cure the adhesive to form the pressure sensitive adhesive tape.
摘要:
A tape is disclosed. The tape includes a metallic foil, an adhesive layer laminated on one surface of the metallic foil and a protective polymeric coating laminated on an opposing second surface of the metallic foil. The protective coating comprises an anti-corrosion agent. The protective coating shields the metallic foil from corrosion and other drawbacks that can occur by environmental exposure. The tape readily can be employed as a busbar tape in photovoltaic cells to provide a cost-effective substitute for the tin-coated copper currently used there.
