Product Overview
HPMC (Hydroxypropyl Methylcellulose, Hypromellose) of construction grade is a key functional ingredient for dry mix mortar, derived from premium refined cotton. The white to off-white fine powder is specially developed for cement and gypsum building formulas, effectively improving mortar physical indicators and stabilizing on-site construction performance.
Available viscosity: 100000–200000 mPa·s (2% Brookfield), custom viscosity supported. The pH of 1% aqueous solution falls within 5.0–8.0. Controlled production process maintains stable product quality, ideal for large-scale continuous production of dry-mix factories. 
Main Application Areas
Our HPMC serves as an essential functional additive for the following dry-mix construction materials:
Interior and exterior wall putty
Ceramic tile adhesives and tile grouts
Gypsum plaster, gypsum leveling mortar and gypsum repair compounds
Masonry mortar and cement rendering mortar
External thermal insulation mortar and base coat protective mortar
Machine spray plaster and other decorative dry-mix products
