1 water retention Hydroxypropyl methylcellulose HPMC for construction avoids moisture infiltration into the wall. The proper amount of water stays in the mortar, so that the cement has a longer time for hydration. The water retention is proportional to the viscosity of the cellulose ether solution in the mortar. The higher the viscosity, the better […]

1.Water retention:  HPMC is mainly used as water retaining agent in dry-mixed mortar. It helps to retain moisture in the mortar, ensuring that the mortar has enough time to hydrate the cementing material after construction. By retaining water, HPMC is contribute to improve the construction performance of mortar and extend its working life. 2.Thickening and wet viscosity:  HPMC can thicken the […]

1.What is the gel temperature of HPMC related to? Normally, for putty powder, the viscosity of HPMC is enough at about 70,000 to 80,000. The main focus is on its water retention performance, while the thickening effect is relatively minor. For mortar, the requirements for HPMC are higher, and the viscosity needs to be around […]
