Rubber-based primer for room temperature repair of rubber gaskets |
摘要 |
The present invention is directed to a primer for application to a rubber gasket for its subsequent repair by a room temperature-curable elastomer. The primer comprises masticated rubber, liquid natural rubber, and carbon black dispersed in a solvent therefor. The method for preparing the rubber gasket surface for repair by a room-temperature-curable elastomer by priming the surface with the inventive primer forms another aspect of the present invention. The rubber gasket which has been primed with the inventive primer forms a further aspect of the present invention. |
