ABSTRACT:
Rubber slivers which are encapsulated within a protective, decorative film of weather-resistant and color-fast resin are used as unconsolidated fall zone material around and under playground equipment. The resin is applied to rubber slivers in the form of an aqueous coating in which a modified acrylic copolymer is mixed with color pigment and rheological additives. The aqueous coating is sprayed onto the rubber slivers as they fall by gravity flow through a drop zone. Thereafter, the aqueous coating is dried and set as the coated rubber particles are conveyed through the exposure zone of a hot air dryer.
