Problem: Calcium Carbonate is a commonly used filler in plastics compounding.Typically, a stearate coating is required to improve dispersiblity of this additive into the compounding process. Traditional coating processes can form undesirable agglomerates that increase the amount of additive required. Due to the high costs of stearates, companies looked for an effective, continuous coatingget price
