Extrudable pressure sensitive non-black adhesive composition and methods for preparing the same

A method for producing a non-black pressure sensitive adhesive composition, the method comprising:

• providing a pre-blend composition that is prepared by combining a butyl rubber, an olefinic polymer or copolymer, and a phenolic resin;
• combining, in a reactor, the pre-blend composition and at least one filler that is selected from the group consisting of clay, talc, mica, titanium dioxide, calcium carbonate, silica, and combinations thereof, to form a blend, wherein the blend optionally further includes one or more of UV stabilizers, antioxidants, and tackifier resins;
• introducing to the reactor an isocyanate and, optionally, one or more of oils, polyurethane catalyst, and liquid carrier to form a mixture;
• and
• subjecting the mixture to conditions sufficient to form the non-black pressure adhesive, which includes a polyurethane within a matrix formed by the butyl rubber.
