WHECELL MC – M40
Modified Methyl Cellulose

Modified MC - M40

WheCell M40 is a Modified Methyl Cellulose grade specifically developed for gypsum-based wall putties and satin finishing compounds that require smooth application behavior, controlled viscosity development, and excellent surface quality. The product is optimized for formulations where creamy consistency, easy spreading, and defect-free surfaces are critical. It ensures stable rheology, good workability, and uniform film formation during application, making it particularly suitable for fine finishing layers. WheCell M40 provides balanced water retention and controlled thickening, supporting reliable processing behavior in both manual and machine-applied gypsum putties.
