HPMC(Hydroxypropyl MethylCellulose)
In building materials, hydroxypropyl methyl cellulose can act as dispersing agents, thickeners and binders, and HPMC is mainly used in the molding of cement mortar and plaster products.  HPMC is used for cement mortar, it can increase adhesion, reduce flocculation, improve viscosity, shrinkage, and water retention, reduce the water loss, enhance the strength and prevent the occurrence of cracks etc.

Knowledge of the use of hydroxypropyl methyl cellulose,such as,
1. Used in the plastering mortar of construction mortar, the high water retention of hydroxypropyl methylcellulose can fully hydrate the cement, significantly increase the bond strength of the cement, and at the same time appropriately increase the tensile strength and shear of the cement Strength, greatly improving the construction effect and improving work efficiency.
2. In the water-resistant putty, hydroxypropyl methylcellulose mainly plays the role of water retention, bonding and lubrication, avoiding cracks and dehydration caused by excessive water loss, and at the same time enhancing the adhesion of the putty and reducing sag during construction This phenomenon makes the construction more smooth.
3. In the plaster series products, hydroxypropyl methylcellulose mainly plays the role of water retention, thickening and lubrication, and has a certain retarding effect at the same time, which solves the problems of hollowing, cracking and failure to reach the initial strength during the construction process , can extend the operating time.
4. In the external wall thermal insulation mortar, hydroxypropyl methylcellulose mainly plays the role of bonding and increasing the strength, so that the thermal insulation sand will be easier to coat, thereby improving work efficiency. High water retention performance can prolong the working time of thermal insulation mortar, improve shrinkage and crack resistance, and improve surface quality.
5. Among the tile adhesives, hydroxypropyl methylcellulose has high water retention, so that it is not necessary to pre-soak or wet the tiles and the base, and significantly improve the bonding strength of the tile adhesive, so that the slurry can last for a construction period Long, delicate, uniform, easy to construct, and has good anti-moisture property.
6. In latex paint, hydroxypropyl methylcellulose can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that the film has good wear resistance, leveling property and adhesion , Improve surface tension. The PH is qualitative, and the miscibility with organic solvents is also good. The high water retention performance makes it have good brushing and leveling properties.
