HPMC, or Hydroxypropyl Methyl Cellulose, is a modified cellulose compound.
CAS:9032-42-2
Improves uniformity, makes mortar easier to spread, and improves resistance to sagging. Enhanced flow, thus improving efficiency.
High water retention, extending the working time of the mortar, improving efficiency, and facilitating the development of high mechanical strength during the setting period.
Air penetration is influenced by controlling the consistency of the mortar, thus eliminating micro-cracks in the coating and creating a high-quality surface finish.
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.
