Hubercarb® Q60
Hubercarb® Q60 is a medium fine ground calcium carbonate produced at Huber’s Quincy, Illinois plant which is known for its natural uniformity producing consistent purity and brightness. The Q100 particle distribution is used in applications to control mine dust, as a mild abrasive, flue gas desulfurization, traffic paints, and oilfield drilling fluids where its low acid insoluble content is useful.
