Patent ID: 7807229

Claim:
A method, comprising: mixing together an un-crosslinked acrylic adhesive, a solvent, and a polyisocyanate crosslinker to form a mixture, wherein the mixture has a first viscosity after mixing; partially reacting the mixture for a first time period, wherein the mixture has a second viscosity that is greater than the first viscosity after the first time period; partially reacting the mixture for a second time period, wherein the mixture has a third viscosity that is greater than the first viscosity and that is less than the second viscosity after the second time period; applying the mixture as a coating to a release liner after the second time period; driving off a portion of the solvent; and further reacting the polyisocyanate crosslinker with the un-crosslinked acrylic adhesive, wherein a resultant crosslinked adhesive exhibits a peel strength in a range between about 2 pounds per square inch and about 8 pounds per square inch at temperatures in a range between about 180 degrees Fahrenheit and about 250 degrees Fahrenheit.
