ABSTRACT:
A method of coloring or coating particles, such as small stones, recycled plastic fragments or recycles rubber fragments comprises mixing the particles with curable liquid resin coating in a mixture, wherein the weight of the coating is within the range of 0.2 percent to 20 percent of the weight of the particles, accelerating the curing when needed by heating, radiation, or additional chemicals to speed the cure, and continuing to agitate the mixture in the mixer until the coating is cured. Preferably, the coated particles are recycled rubber fragments, and the particle size is larger than 0.1 mm, preferably in the range of 0.5 mm to 10 mm. The colored particles can be used as a cheap substitute colored EPTM granules.
