METHOD FOR PROTECTING A TYRE AGAINST OZONE

摘要

The invention concerns a method for protecting against ozone at least part of the outer surface of a tyre, whereof the composition is based on substantially saturated diene elastomers which consists in: treating the surface of the vulcanised tyre so as to functionalise the elastomers of said surface; applying on said treated surface at least a coat consisting of an aqueous dispersion of polyurethane; allowing said coat to dry until a protective coating is formed.
