why HPMC is necessary in construction?

Construction industry: As a water-retaining agent and retarder for cement mortar, it makes the mortar pumpable. Used as a binder in plastering paste, gypsum, putty powder or other building materials to improve spreadability and prolong operation time. It is used as a paste for ceramic tile, marble, plastic decoration, as a paste enhancer, and it can also reduce the amount of cement. The water retention of HPMC can prevent the slurry from cracking due to drying too fast after application, and enhance the strength after hardening.
1.1 Cement mortar: Improve the dispersibility of cement-sand, greatly improve the plasticity and water retention of mortar, and have an effect on preventing cracks and enhance the strength of cement.
1.2 Tile cement: Improve the plasticity and water retention of pressed tile mortar, improve the bonding force of tiles, and prevent chalking.
1.3 Gypsum coagulation slurry: improve water retention and processability, and improve adhesion to the substrate.
1.4 Joint cement: added to the joint cement for gypsum board to improve fluidity and water retention.
1.5. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.
1.6. Coating industry: as a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents.
