ABSTRACT:
This invention represents an improvement in the method for making beater-saturated products by forming a slurry of asbestos fibers in water, precipitating a synthetic, non-film forming, organic binder in particulate form on said fibers to form a slurry of coated fibers, draining the slurry of coated fibers and forming a product therefrom. The improvement in accordance with this invention comprises controlling the drainage time of the slurry of coated fibers by adding to such slurry a film-forming secondary binder.
