Abstract

Methods for bonding polymeric substrates to hydroxylated surfaces such as glass are disclosed. The polymeric substrates may be elastomeric substrates such as a natural or synthetic rubber. The method may comprise applying a compound comprising at least one alkoxy silane moiety and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor to one of the substrates. The nitrosoaromatic moiety may be a nitrosobenzene. The nitrosoaromatic precursor may be a nitrosobenzene precursor, such as at least one of a quinone dioxime or a quinone oxime. Novel primers and compounds suitable for use in the bonding process are also disclosed.
