200000cps HPMC Construction Grade Hydroxypropyl Methyl Cellulose Good Anti‑Sagging Thickener For Interior Exterior Wall Putty

Product Introduction

Construction‑Grade HPMC (Hydroxypropyl Methyl Cellulose) is a non‑ionic cellulose manufactured from high‑purity cotton raw material through etherification reaction. This 200000cps viscosity grade features excellent water‑retention performance, anti‑sagging property, good workability and thickening effect, widely used for dry‑mix mortar industry.
It effectively prevents mortar from rapid dehydration and cracking, extends open time, improves construction smoothness, avoids sagging during plastering and tiling work. Our HPMC powder dissolves quickly in cold water without agglomeration, bringing stable viscosity for your end products.

Key Features

• Excellent water retention: Avoid quick water loss, improve cement hydration, reduce cracking risk
• Good anti‑sagging performance: No slipping or sagging for thick‑layer plaster & tile adhesive
• Superior thickening & lubricity: Enhance mortar workability, make construction easier
• Fast cold‑water dissolution, no lump
• Stable viscosity, consistent batch‑to‑batch quality
• Good compatibility with other dry‑mix mortar additives

Main Applications

• Wall putty / Skim coat  Improve water‑retention and workability, prevent cracking and powder‑falling for interior & exterior wall putty, achieve smooth plastering surface.
• Cement‑based tile adhesive  Enhance anti‑sagging performance, avoid tile slipping; extend open time, guarantee strong bonding strength for tile installation.
• Exterior wall thermal insulation mortar  Reduce rapid water loss during construction, improve mortar cohesion, optimize anti‑cracking performance for external insulation system.
• Gypsum plaster & gypsum‑based products  Control setting time, improve lubricity and workability, avoid dry‑out cracking of gypsum plaster, joint filler and gypsum casting materials.
• Self‑leveling compound  Offer proper thickening and anti‑segregation effect, keep uniform fluidity, prevent sedimentation for floor self‑leveling mortar.
• Repair mortar, masonry mortar  Great water retention keeps sufficient water for cement hydration; boost adhesion strength, reduce shrinkage crack for repair and brick‑laying mortar.
