Low-priced industrial chemical HPMC is used for interior and exterior wall putty powder

Hydroxypropyl methylcellulose (HPMC) is commonly used in interior and exterior wall putty powder formulations due to its various beneficial properties. The applications of HPMC in wall putty production are as follows:

The role of HPMC in wall putty powder:

Water retention:

HPMC acts as a water retaining agent to prevent rapid loss of water during the setting process of the putty. This ensures proper hydration and helps improve workability.

Thickening:

It has thickening properties that prevent the putty from sagging or collapsing when applied to vertical surfaces. This enhances ease of application and helps make the surface smoother.

Improve adhesion:

HPMC enhances putty adhesion to the substrate, promoting better bonding and reducing the risk of cracking or peeling.

Workability and opening times:

HPMC helps keep the application performance of the putty consistent over a long period of time, known as open time. This makes it easier for workers to apply and finish the putty.

Reduce shrinkage:

By controlling water evaporation, HPMC minimizes putty shrinkage during the drying process. This helps improve the stability and crack resistance of the final product.

Set time control:

Adjusting the amount of HPMC can control the setting time of wall putty to meet different application requirements.
