Key Performance Advantages of Gypsum-Specific HPMC
Enhanced Water Retention
Water retention is one of the most critical parameters for gypsum-based materials. The addition of HPMC effectively prevents premature moisture loss, extends the working time, and prevents issues such as drying cracks and powdering.
Improved Workability and Flow
HPMC enhances the flow properties and workability of the slurry, making plastering and troweling smoother and thereby boosting construction efficiency.
Strengthened Bonding Adhesion
An appropriate dosage of HPMC significantly improves the adhesion between gypsum products and the substrate, thereby preventing potential construction defects such as hollowing and cracking.
Excellent Retarding Properties
Specially formulated HPMC products possess inherent retarding effects, which help to extend the material’s open time and workability window.
Improved Surface Finish
With the addition of HPMC, the gypsum surface becomes finer and smoother, making subsequent finishing treatments easier and more trouble-free.
