ABSTRACT:
An aqueous dispersion coating for rubber and polymer substrates comprises a blend of a polysiloxane and a curable polyurethane and various additives such as a urethane crosslinking agent, a heat resistant filler, and the like. The aqueous dispersion coating reduces the noise upon contact or movement of the coated substrate with an article and maintains the initial static coefficient of friction therewith over a period of time. A desired end use is as a coating on vehicle weatherstrips such as for doors, trunks, and other enclosing articles.
