Hubercarb® M300 is an medium-fine ground calcium carbonate produced from a uniform, high calcium limestone deposit in Marble Falls, Texas. Carefully controlled particle distribution allows M300 to be used a wide range of applications including paints, coatings, adhesives, caulks, and concrete building products. Acid solubility above 92% and location make M300 ideal for use in oilfield drilling fluids.
