Hydroxypropyl Methyl Cellulose for Putty

Hydroxypropyl Methyl Cellulose for Putty

Wall putty plays a vital role in preparing walls for painting and finishing. Whether applied on interior or exterior surfaces, putty must offer smoothness, adhesion, and resistance to cracking. To achieve these qualities, modern formulations increasingly rely on additives like Hydroxypropyl Methyl Cellulose (HPMC). Zongsheng provides high-quality HPMC tailored for use in both cement-based and gypsum-based putty.

What Is Wall Putty and Why It Matters

Wall putty is a fine powder material that is mixed with water to create a paste used to level surfaces, fill imperfections, and provide a uniform base for paint. It improves the paint’s appearance, durability, and longevity.

For manufacturers, the challenge lies in creating a putty that offers good workability, adhesion, and drying performance. That’s where HPMC comes into play, offering key functional benefits.

How HPMC Improves Wall Putty Formulations

Hydroxypropyl Methyl Cellulose is a water-soluble polymer derived from natural cellulose. It acts as a rheology modifier and water-retaining agent, essential for ensuring smooth application and high-quality finishes.

Key Functions of HPMC in Wall Putty

Water Retention

HPMC helps retain moisture in the putty mix, allowing for proper curing and hydration. This improves the bonding strength of the putty to the substrate and prevents premature drying.

Better Workability

HPMC enhances the smoothness and spreadability of wall putty, making it easier to apply and spread with a trowel. This leads to reduced labor effort and better surface leveling.

Crack Resistance

By controlling water evaporation and improving flexibility, HPMC minimizes the formation of hairline cracks during the drying process, especially in high-temperature conditions.

Increased Open Time

Putty with HPMC maintains its workable state for longer periods, providing more time for application and finishing without affecting performance.

Anti-Sagging Performance

Especially in vertical applications, HPMC improves the paste’s ability to stay in place, preventing sagging or dripping that can affect surface uniformity.
