In the application of building materials, hydroxypropyl methylcellulose has its unique properties from mixing to dispersion to construction, as follows:
Firstly, compounding and configuration
1.Cement mortar: HPMC improves the dispersibility of cement-sand, greatly improves the plasticity and water retention of the mortar, has an effect on preventing cracks, and can enhance the strength of cement.
2. Tile cement: HPMC improves the plasticity and water retention of the pressed tile mortar, improves the adhesive force of the tile, and prevents chalking.
3. Coating of asbestos and other refractory materials: HPMC is used as a suspension agent, fluidity improver, and also improves the adhesion to the substrate.
The instant Hydroxypropyl methylcellulose (HPMC) disperses quickly in cold water and disappears in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and does not really dissolve. In about 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid.

hydroxypropyl methylcellulose(HPMC) CAS no. : 9004-65-3,is white to slightly off-white fibrous or granular powder,it is a synthetic modified natural polymer,and a nonionic cellulose ether with odorless and tasteless. HPMC can increase properties of gelation, surface activity, water retention,thickening, adhesion, dispersion, emulsification, film-forming, suspension, providing protective colloids and other properties.
