Elastomer toughened two-part acrylic monomer adhesives which employ styrene-butadiene block copolymer rubbers as the elastomer have improved heat resistance properties at temperatures typical of industrial paint bake ovens. The adhesives include: in one part an acrylic monomer, at least 33% by weight of the rubber dissolved in the monomer, and a free radical catalyst system free of organic sulfonyl chloride; and in the other part a polymerization activator such as an amine-aldehyde condensation product. |
