Abstract
A composition is disclosed that comprises a blend of: A) at least one hydrolyzable polysulfide silane; and B) at least one coupling agent selected from the group consisting of hydrolyzable tetraalkoxysilanes, hydrolyzable oligomers of tetraalkoxysilanes, and mixtures thereof. An article of manufacture comprising an elastomer, a mineral filler, and the above composition is also disclosed.
