Construction Grade Hydroxypropyl Methyl Cellulose (HPMC) is a premium-grade chemical raw material widely used in wall putty, dry-mix mortar, and cement-based applications. Sourced from refined cotton and processed under ISO9001 standards, this product offers excellent water retention, improved workability, and superior bonding strength—making it an essential additive in construction projects.
HPMC is a non-ionic cellulose ether and appears as a white, odorless, tasteless powder. It is highly versatile and compatible with different cement and gypsum-based formulations. The product is especially effective in enhancing wall putty adhesion, preventing cracking, and extending open time.
