Is used in most water-base muds to increase and maintain pH and alkalinity. It is a hazardous material to handle because it is very caustic and gives off heat when dissolved in water. CMC is also used in some cement mix plasticizers. This helps homogenize cement mixes, preventing segregation of sands and cement, decreases the amount of water required in a mix and increases workability of the cement product, be it mortar, render or concrete. We offer CMC in both low viscosity and high viscosity. Both of our CMC types are API-certified.
