METHODS FOR RETREADING TIRES EMPLOYING TREAD COMPOSITES MADE WITH DRY-TRANSFER CEMENT COMPOSITE

摘要

A process for retreading a tire, the process comprising the steps of providing a liquid rubber cement composition including a solvent, providing a release liner, applying the liquid cement composition to the release liner to form a wet film on said release liner, allowing the solvent to evaporate to thereby convert the wet film to a dried film on the release liner and thereby form a dry-transfer cement composite, providing a cured rubber component having first and second planar surfaces, where the first planar surface includes a tread pattern, adhering the dried film to the second planar surface of the cured rubber component to thereby form a tread composite, and preparing a retreaded tire using the tread composite.
