Application of Hydroxypropyl Methyl Cellulose in Dry Mix Mortar for Construction

Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether derived from natural cellulose through chemical modification. It is a non-toxic, odorless, white to off-white powder that dissolves in cold water to form a transparent, viscous solution. Due to its unique chemical structure, HPMC imparts several key properties to dry-mix mortars: thickening, water retention, dispersion, and film-forming. These characteristics make it an indispensable additive in mortars based on cement, gypsum, and other materials.
