Hydroxypropyl Methylcellulose for Gypsum Plaster
TENESSY Hydroxypropyl Methylcellulose (HPMC) is a high-performance cellulose ether derived from natural cotton cellulose. It serves as a thickener, water-retention agent, and workability enhancer in a wide range of gypsum-based plasters and renders.
In gypsum plaster formulations, TENESSY HPMC ensures a smooth and consistent mix, prevents cracks and powdering, and gives excellent adhesion to walls and ceilings. Whether used in hand-applied or machine-sprayed systems, it helps achieve stable performance and a flawless finish.
Main Functions of HPMC in Gypsum Plaster
Gypsum plaster, also known as plaster of Paris or gypsum rendering, requires proper water management and smooth workability to deliver a high-quality surface. HPMC is a key additive that optimizes these properties and enhances both production and on-site performance.
- Water Retention: Keeps sufficient moisture in the mix, ensuring complete gypsum hydration and uniform setting.
- Improved Workability: Provides better lubrication and spreadability for easy troweling and finishing.
- Enhanced Adhesion: Increases bond strength to different substrates, preventing delamination and dusting.
- Crack & Shrinkage Control: Improves flexibility, reducing shrinkage cracks during drying.
- Setting Time Adjustment: Offers controlled set time for improved open time and work convenience.
- Consistency & Stability: Prevents segregation and ensures uniform texture throughout application.
