Abstract

Compositions having a compound comprising at least one alkoxy silane moiety, and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor and combinations thereof; and an aqueous or water containing carrier medium are provided for use in polymer bonding. The water may allow for substantial hydrolysis of the compound. Suitable polymers may have diene or allylic functionality within the polymer chain, for example an elastomer such as a natural or synthetic rubber. The polymers may be bonded to metals or substrates with hydroxylated surfaces such as glass. The nitrosobenzene precursor may be at least one of a quinone dioxime or a quinone oxime.
