Commonly used in gypsum-based products include hydroxypropyl methylcellulose (HPMC), methyl hydroxyethyl (MHEC), redispersible latex powder (RDP), etc.
Main functions
▶Water retention: helps to maintain moisture in gypsum slurry and reduce the rapid evaporation of moisture, thereby extending the operability time of gypsum and ensuring smooth construction.
▶Thickening: Increase the viscosity of gypsum slurry, prevent sagging and dripping, and improve the convenience of construction and surface smoothness.
▶Improve construction performance: Make gypsum slurry softer and smoother, easy to apply and scrape, and improve construction efficiency and quality.
▶Improve bonding performance: Enhance the bonding force between gypsum and the base layer, and ensure the firm bonding of the gypsum layer and the base layer.
▶Improve crack resistance: Reduce shrinkage cracks during the hardening process of gypsum, and enhance the integrity and durability of gypsum-based products.
▶Stabilize and improve the performance of gypsum: Maintain the consistency and stability of the performance of gypsum-based products under different environmental conditions.
