Abstract
A process for the production of a vulcanized latex protective coating bonded to the surface of an asbestos-cement article, particularly a pipe, is disclosed. The process includes a step whereby the latex coating is applied before autoclaving to the article, and becomes a hard, protective bonded layer during the autoclaving process.
