The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
ISO certified Hydroxypropyl Methyl Cellulose (HPMC) powder is readily available for building materials, including gypsum putty. ISO certification indicates that the HPMC powder meets the international standards set by the International Organization for Standardization.
HPMC offers several advantages that enhance the performance of building materials:
Improved workability: HPMC acts as a thickener, increasing the viscosity of the material. This makes it easier to apply smoothly and reduces the risk of sagging or dripping, especially for overhead applications.
Enhanced water retention: HPMC helps the material retain moisture, preventing it from drying out too quickly. This allows for a longer working time, giving applicators more time to manipulate and finish the material before it sets. Reduced moisture evaporation also helps prevent cracking and shrinkage as the material dries.
Better adhesion: HPMC can improve the adhesion of the material to the substrate, creating a stronger bond. This is crucial for ensuring a durable and long-lasting finish.
Smoother finish: HPMC helps create a smoother surface, minimizing the need for extensive sanding after application.
