Unleashing the Potential of HPMC in Gypsum Plaster and Beyond
October 22nd 2024
1. High water retention
Cellulose has a high water-holding capacity. This attribute makes it useful to improve resistance, prevent cracking, and enhance gypsum plaster’s overall appearance. It also boosts surface uniformity, lubrication, and adhesion when applied to gypsum plaster in putty and other construction works.
2. Thickening property
HPMC is the right material for you if you want to increase the tensile strength of gypsum plaster and other construction material. It acts as an interface agent. That is, it improves gypsum plaster flexural strength and increases bonding strength.
3. Highly stable
HPMC’s outstanding film-forming properties and high resistance to degrading enzymes help stabilize gypsum plaster pH and enhance its salt discharge performance.
Others include dispersibility, constructability, and adhesive strength. Also, HPMC has effects on the setting time, pumpability, and workability of gypsum plaster composition. Overall, it enhances construction efficiency and guides against weathering after exposure of building surfaces to water-soluble salts.
