HPMC solubility in water has two types: surface-treated HPMC and non-surfaced treated HPMC. 1 Solubility of Surface-Treated HPMC in Cold Water When surface-treated HPMC is added to cold water, it disperses into the water without exhibiting any viscosity. After stirring and waiting for approximately 2 minutes, the solution thickens and becomes viscous. This is attributed to […]

1. Mortar and cement-based products A. Improve workability HPMC is often added to mortars and cement-based products to improve workability. It acts as a water retaining agent, preventing rapid loss of water during the setting process. This results in better maneuverability and easier application. b. Increase adhesion Adding HPMC to mortar improves adhesion to a […]

● Water Retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have a greater impact on its water retention performance. Under the same conditions, the higher the viscosity of HPMC, the better the water retention; The higher content, the better the water retention. Generally, a small […]

Hydroxy propyl methyl cellulose (HPMC) is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecula and protective colloid properties of surface activity and maintain moisture function properties ect.cellulose through series of chemical processing and achieved. HPMC is white powder with good water solubility. It has thickening, adhesion ,dispersing,emulsifying, film, suspended, adsorption, gel. In the course of construction,HPMC […]

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 […]

HPMC, also known as hydroxypropyl methylcellulose, plays a crucial role in enhancing adhesion in tile cement. This key ingredient is commonly used in construction materials due to its effectiveness in improving the bonding properties of tile cement. It acts as a binder, creating a strong and durable bond between the tiles and the substrate. When […]

In dry mix mortar, adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar. ● Water Retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have […]

If the hot soluble type (Non-surface treated) HPMC is added directly to the water, agglomeration will occur before dissolution. However, dissolving in this way is very slow and difficult. Here we recommend three dissolution methods for end users based on different applications： 1 Hot water dissolution method: Since HPMC is not dissolved in hot water, […]

1. Water Retention HPMC has excellent water-retaining properties. When mixed with skim coat materials, it helps to keep the mixture workable for extended periods. This is particularly advantageous during application, as it prevents the mixture from drying out too quickly, allowing for even and consistent application. The enhanced workability reduces the risk of cracking and […]
