The similar performances between HPMC and MHEC in construction chemicals
January 3rd 2025
Used as thickener, dispersant, water retention agent and air-entraining agent etc. Mainly used in cement and gypsum based dry mix mortar to increase bond strength, workability, and water retention. Reduce water loss on concrete surface, preventing cracks and increase scrape area. It is widely used in wall plaster and tile adhesive products
In paints, as a protective colloid, HPMC and MHEC can be used in the polymerization of vinyl acetate emulsion to improve the stability of the polymerization system in a wide pH range. Use pigments, fillers and other additives in finished product manufacturing to evenly disperse, stabilize and provide thickening effect.
