HPMC For Putty Powder

HPMC (hydroxypropyl methylcellulose) is a common functional additive widely used in putty powder.

Wall putty (Skim Coat) is a decorative material that makes the wall surface smooth and can be used for interior and exterior wall decoration. Cellulose HPMC plays a vital role in wall putty (putty layer) to improve the key properties such as water retention, open time, crack resistance, workability, etc. Dingao HPMC for wall putty is characterized by high water retention, dispersion, good fineness, good workability and easy dissolution. It is suitable for dry mortar construction, internal and external wall putty powder (paste), putty powder)

The following are several main applications of HPMC for putty powder:

1. Increase viscosity: HPMC can increase the viscosity of putty powder, making it easier to apply and apply. By adjusting the amount of HPMC added, the fluidity of the putty powder can be controlled to keep it in the desired position on vertical or inclined surfaces.

2. Improve adhesion: HPMC has good adhesion and can enhance the bonding force between the putty powder and the base surface. It can form a uniform adhesive film so that the putty powder can firmly adhere to the wall or other base surface.

3. Adjust drying time: HPMC can meet different construction requirements by adjusting the drying speed of putty powder. It can delay the drying time of putty powder, giving construction workers enough time for trimming and polishing.

4. Improve weather resistance: HPMC can improve the weather resistance of putty powder and make it stable under different environmental conditions. It can reduce the possibility of putty powder getting wet, cracking and falling off, and improve its service life and appearance quality.

1. Control contractility: HPMC can control the shrinkage of putty powder and reduce volume changes during drying. This helps reduce the risk of the putty powder cracking or deforming after it dries.
