HPMC

Application areas

The main roles of HPMC (Hydroxypropyl Methyl Cellulose) in coatings are as follows:
- Thickening and Leveling: Adjusts coating viscosity, improves leveling property, prevents sagging during brushing, and enhances coating uniformity.
- Dispersion and Stability: Helps pigments and fillers disperse evenly, prevents sedimentation and delamination, and strengthens system stability.
- Film Formation Assistance: Improves coating adhesion, aids in film formation, and enhances coating flexibility and crack resistance.
- Water Retention and Slow Drying: Delays water evaporation, extends open time, and facilitates construction operations (such as troweling and rolling).
- Anti-Splash Property: Increases coating thixotropy, reduces splashing during construction, and improves operational convenience.
