Methyl Cellulose (MC) for Dry-Mix Mortar
CAS Number: 9004-67-5
Methyl cellulose (MC) is a non-ionic cellulose ether used in dry-mix mortars, renders, and plasters as a water retention agent and thickener. It dissolves readily in cold water and provides stable viscosity, good workability, and controlled water retention. MC is particularly valued in masonry mortars, render coats, and floor leveling compounds where consistent water management is critical for proper curing and bond development.
