Role of HPMC & MHEC in Wall Putty
- •Anti-Sagging and Thixotropy
- Improves vertical hold and consistency, allowing thick applications without dripping or
sagging. - •Water retention effect
HPMC can prolong the drying time of putty powder, assist in the full reaction of materials
such as lime and calcium under the influence of water, and enhance the hardening strength. - •Thickening effect
HPMC achieves this by providing a thickening effect, enabling the putty powder to be
uniformly suspended. This prevents runny phenomena during the construction process and
maintains the stability of the slurry.
