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, 8ypsum mortar, etc.

The performance of HPMC in dry mortar:
A. Excellent water retention can ffectively prevent the mortar from losing water so quickly as to lose its operabiliy, 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 fficiency;
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.
