ABSTRACT:
The present invention relates to dimedone functional self-bonding room temperature vulcanizable silicone rubber compositions. The self-bond additive is selected from silyl maleates, silyl fumarates, silyl succinates, silyl isocyanurates and mixtures thereof. Preferably the self-bonding additive is prereacted with the cross-linking agent before they are incorporated into the RTV composition. This prereaction of the self-bonding additive and the cross-linking agent imparts shelf-stability to the composition.
