HEMC Hydroxyethyl Methyl Cellulose is a non-ionic cellulose ether used to improve water retention, open time, and workability in cement- and gypsum-based systems. It provides stable viscosity development and enhances application performance, especially in dry-mix mortar formulations requiring smooth consistency and improved adhesion.
