The coating process starts with raw sand that is produced at one of our mines and shipped to Rochelle as substrate. The plant then processes the sand coating the grain with a thin layer of resin. This coating results in a proppant with improved down-hole performance due to higher crush strength and improved "roundness" of the grains.
