English alias: HPMC

2： Main uses

1. Construction industry: As a water retaining agent and retarder for cement mortar, it makes the mortar pumpable. Used as a binder in gypsum, plaster, putty powder, or other building materials to improve spreading and extend working time. It can be used for pasting ceramic tiles, marble, plastic decorations, pasting reinforcement, and can also reduce the amount of cement used. The water retention performance of HPMC prevents the slurry from cracking due to rapid drying after construction, enhancing the strength after hardening.

2. Ceramic manufacturing industry: widely used as a binder in the manufacturing of ceramic products.

3. Coatings Industry: Used as a thickener, dispersant, and stabilizer in the coatings industry, it has good compatibility with water or organic solvents. As a paint remover.
