HPMC for self-leveling and HPMC for putty
The HPMC (hydroxypropyl methylcellulose) used in self-leveling mortar and putty is the same product, but the specifications of HPMC are different, so you need to pay attention to the distinction when purchasing.
Similarities:
- Composition: Both are prepared based on hydroxypropyl methylcellulose. HPMC is obtained from natural cellulose through chemical treatment and has excellent thickening and binding capabilities.
- Function: The main function of HPMC in self-leveling mortar and putty is to thicken, improve fluidity, improve adhesion and water retention.
the difference:
- Viscosity requirements: Self-leveling mortar usually requires a lower viscosity to achieve better self-leveling performance, while putty requires a relatively higher viscosity to better fill and smooth wall defects.
- Adding amount: Due to different application requirements, the amount of HPMC added to self-leveling mortar and putty may be different. The specific addition amount should be adjusted according to the product production formula.
