摘要:
The invention relates to an aqueous polyvinyl alcohol/polyvinyl acetate-based composition which can be applied to a cured rubber surface, such as the white sidewall of a tire, to provide a protective coating against staining and scuffing. Preferably, the aqueous composition includes a polysiloxane agent for increasing the scuff resistance and high humidity resistance.
