Abstract:
The present invention provides an acrylate/silicone pressure-sensitive adhesive tape having improved adhesion to painted surfaces and low temperature performance. The pressure-sensitive adhesive tape comprises: (a) a pressure-sensitive adhesive layer comprising a polymerized pressure sensitive adhesive composition wherein said pressure sensitive adhesive composition comprises: (I) about 25 to about 99 weight percent of polymer of the formula wherein: X, Y, D, R, R1, R2, R3, R4, and n are defined in the specification; (II) about 1 to about 75 weight percent free radically polymerizable vinyl monomer which is capable of copolymerizing with the polymer wherein said free radically polymerizable monomer comprises: (i) about 5 to about 100 parts by weight of an acidic monomer selected from the group consisting of methacrylic acid, acrylic acid, and mixtures thereof; (ii) about 0 to about 95 parts by weight of an acrylate monomer selected from the group consisting of esters of acrylic acid comprising 4 to 21 carbon atoms and esters of methacrylic acid comprising 5 to 21 carbon atoms and mixtures thereof; based upon 100 parts total by weight of said free radically polymerizable monomer; wherein the weight percentages set forth in elements,(I) and (II) are based upon the total weight of the polymer of element (I) plus the monomer of element (II); and (III) a sufficient amount of a silicate MQ tackifying resin to impart a degree of adhesive tack to the cured composition at the use temperature; and (b) a foam layer which is coated on at least one side with the adhesive layer. The present invention also provides the pressure sensitive adhesive composition and pressure sensitive adhesive.
