Does HPMC participate in chemical reactions on Skim coat/Wall putty?
HPMC mainly have the effect of thickening, water-retention and constructability in Putty powder:
- Thickening: HPMC can thicken the solution and give the solution suspension and consistency effect. Have good effect of anti-sagging.
- Water-retention: Let putty powder dry more slowly, assist hydrated reaction of ash-calcium.
- Constructability: HPMC’s lubrication action gives putty powder good constructability.
