Abstract
Methods of forming a pressure sensitive adhesive (PSA) are provided. The methods may be suitable for aircraft exterior applications. A particular method includes mixing together an un-crosslinked acrylic adhesive, a solvent, and a polyisocyanate crosslinker to form a mixture. The method also includes driving off a portion of the solvent. The method further includes reacting the polyisocyanate crosslinker with the un-crosslinked acrylic adhesive. A resultant crosslinked adhesive exhibits a peel strength in a range between around 2 pounds per square inch and around 8 pounds per square inch at temperatures in a range between around 180 degrees Fahrenheit and around 250 degrees Fahrenheit.
