Product Description

Hydroxypropyl methyl cellulose has excellent stability and compatibility, and has extremely wide uses in the building materials industry. HPMC can be used as water retention agents, thickeners, and retarders and adhesive. The HPMC plays an important role in dry-mixed mortar, self-leveling mortar, tile adhesive, wall putty, gypsum mortar, etc.
The performance of HPMC in dry mortar:
A. Excellent water retention can effectively prevent the mortar from losing water so quickly as to lose its operability, and avoid rapid surface drying and cracking, and make the mortar have a longer opening time and adjustment time;
B. The thickening effect of HPMC can control the mortar to achieve the best consistency, improve the cohesion of the mortar, achieve anti-sagging effect, improve operability, and greatly improve construction efficiency;
C. It can improve the bonding strength of the mortar, and it can ensure sufficient moisture and time to fully hydrate the cement, thereby ensuring that the mortar has better bonding performance and strength even in a high temperature environment.
Surface Treatment of HPMC
Surface treatment products are specially developed to avoid clumping in wet mixing applications. When preparing a solution for a surface-treated product, we can pour the product directly into cold water, and the HPMC will quickly disperse into the water and slowly form a viscous solution within a certain period of time. The delaved dissolution time is usually about 5 minutes when using surface-treated products (based on PH-7), but if the PH value of the solution increases, the delayed dissolution time wilbe shortened. The delayed dissolution time can be adjusted according to customer needs, some products with surface treatment are indicated by the suffix "S" in the brand, such as MPC40TS.
