How does cellulose ether benefit gypsum-based wall surfaces?
Click here to get more.
Gypsum-based wall surfaces use plastered gypsum instead of traditional cementitious materials. They are used for plastering and leveling indoor walls and ceilings in buildings.
Plastered gypsum forms strong adhesion with various inorganic substrates. It can prevent issues with the wall surfaces. That includes hollowing, cracking, and detachment seen in traditional cement mortar layers.
Many factors affect the evaporation rate of moisture in gypsum-based products. That includes air temperature, humidity, wind speed, etc.
Excellent HPMC products can address moisture retention issues. It can help disperse within gypsum slurry. And envelop all solid particles to form a wetting film.
This film can release moisture over a considerable period. Facilitating hydration with inorganic binding materials. Thus, it ensures the bonding strength and compressive strength of the materials.

mPa.s (NDJ-1, 2% solution, 20&#;)Gypsum plaster is a popular construction material known for its excellent properties, such as fire resistance and sound insulation. To further improve its workability, adhesion, and performance, Hydroxypropyl Methyl Cellulose (HPMC) is often used as an additive. In this article, we will explore the significance of HPMC for gypsum plaster and its various advantages in the construction industry.
The Role Of HPMC In Gypsum Plaster:
Improved Workability:
HPMC enhances the workability and ease of application of gypsum plaster, allowing it to spread more smoothly and efficiently on a variety of surfaces. Its water-retaining properties prevent rapid drying, allowing contractors to achieve consistent results without compromising quality.
Enhanced Adhesion:
SLEO Chemical are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
HPMC helps improve the adhesion of gypsum plaster to dissimilar substrates, promoting a strong bond and reducing the risk of delamination or cracking over time. This produces a long-lasting, durable plaster finish.
Superior Crack Resistance:
HPMC-treated plaster is more resistant to cracking, reducing the likelihood of cracks forming due to shrinkage or movement. This is particularly beneficial in areas prone to temperature fluctuations or structural changes.
OPTIMAL OPEN TIME:
HPMC extends the open time of the plaster, giving craftsmen more time to perfect their finishing touches. This increase in machinability means improved aesthetics and a more refined final appearance.
Controlled Water Retention:
The controlled water absorption and release capabilities of HPMC ensure proper curing of the plaster, allowing for even drying and minimizing surface imperfections. This controlled hydration helps create an even, flawless finish.
Description of HPMC for gypsum plasters:
Water Retention:
HPMC serves as a water retention agent in gypsum plasters, helping to maintain the optimal moisture level within the plaster mix. This extended water retention ensures that the plaster remains workable for a longer period, allowing for easier application and smoother finishing.
Improved Workability:
By enhancing water retention, HPMC enhances the workability of gypsum plasters, making them easier to mix, apply, and spread onto surfaces. The improved workability results in better coverage, reduced material waste, and enhanced overall productivity during plastering operations.
Reduced Sagging and Slumping:
The addition of HPMC helps prevent sagging and slumping of gypsum plasters, particularly on vertical surfaces such as walls and ceilings. This improved sag resistance ensures that the plaster adheres evenly to the substrate without dripping or sliding, resulting in a uniform and aesthetically pleasing finish.
Enhanced Adhesion:
HPMC improves the adhesion of gypsum plasters to various substrates, including masonry, concrete, wood, and drywall. This enhanced adhesion ensures a strong bond between the plaster and the substrate, minimizing the risk of delamination or detachment over time.
Crack Resistance:
HPMC contributes to the crack resistance of gypsum plasters by imparting flexibility to the hardened material. This increased flexibility allows the plaster to accommodate minor movements or substrate expansion and contraction without cracking or fracturing, ensuring long-term durability and structural integrity.
Surface Smoothness:
Gypsum plasters formulated with HPMC exhibit improved surface smoothness and finish, resulting in a uniform and seamless appearance. The addition of HPMC helps minimize surface imperfections such as ridges, bumps, and air voids, allowing for easier painting or decoration after plastering.
Compatibility:
HPMC is compatible with other additives commonly used in gypsum plaster formulations, including setting accelerators, retarders, and air-entraining agents. This compatibility allows formulators to tailor the properties of gypsum plasters to meet specific performance requirements while maintaining consistency and stability.
In summary, Hydroxypropyl methylcellulose (HPMC) plays a crucial role in enhancing the performance and workability of gypsum plasters, providing improved water retention, workability, sag resistance, adhesion, crack resistance, surface smoothness, and compatibility with other additives. Its use contributes to the production of high-quality gypsum plaster formulations suitable for a wide range of interior and exterior plastering applications.
