Culminal C9164 methylhydroxyethylcellulose provides excellent performance for cementitious tile adhesives and External Insulation Finish Systems (EIFS) mortars. The special modification improves wet adhesion (contact area) and prolongs the open time of tile adhesives significantly. This product exhibits outstanding water retention and thus reduces the absorption of water into substrates. In cementitious tile adhesives, it offers high sag resistance along with outstanding workability.

Culminal methylcellulose derivatives are cellulose ethers that, when dissolved in water, offer a variety of functional properties. Culminal products are powders. They are used as thickeners, protective colloids, stabilizers, suspending aids and water-retention agents in many industrial applications.
