HPMC hydroxypropyl methylcellulose in building materials 1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of the mortar, and have an effect on preventing cracks, which can enhance the strength of the cement. 2. Tile cement: improve the plasticity, water retention of the pressed tile mortar, improve the bonding strength of the tile, prevent powdering. 3. Gypsum coagulation slurry: Improves water retention and processability, and improves the adhesion to the substrate. 4. Seam cement: added to the joint cement for gypsum board to improve fluidity and water retention.

5. Coatings: As a plasticizer for latex coatings, it has an effect on improving the handling properties and fluidity of coatings and putty powder.
