Carboxymethyl Cellulose (CMC) is a high-performance cellulose ether derivative widely used in the construction industry due to its unique properties that enhance the quality and performance of building materials. Construction-grade CMC is specifically formulated to meet the stringent requirements of construction applications, providing excellent water retention, workability, and stability in various cement-based and gypsum-based products.
Construction-grade Carboxymethyl Cellulose (CMC) is a vital ingredient that significantly enhances the performance of cement and gypsum-based materials. Its properties, such as water retention, improved workability, and enhanced adhesion, make it indispensable in modern construction.
Whether used in mortars, plasters, tile adhesives, or self-leveling compounds, CMC helps deliver superior quality and durability, ensuring that construction projects meet the highest standards of excellence.
Water Retention: One of the primary benefits of construction-grade CMC is its superior water retention capability. When added to cement or gypsum-based products, CMC helps retain water within the mixture, ensuring optimal hydration of cement particles. This leads to improved curing, reduced cracking, and enhanced overall strength and durability of the final product.
Improved Workability: CMC improves the workability of construction materials by providing a smooth, creamy consistency. This makes it easier to apply and spread cement, mortar, or plaster, resulting in a more uniform finish. The improved workability also reduces the effort and time required during application, leading to increased efficiency on construction sites.
Enhanced Adhesion: By modifying the rheological properties of the mixture, CMC enhances the adhesion of mortars and plasters to various substrates, including concrete, bricks, and blocks. This ensures better bonding strength, reducing the risk of delamination and enhancing the durability of coatings and layers.
Sag Resistance: Construction-grade CMC provides excellent sag resistance, preventing materials from sliding off vertical surfaces during application. This is particularly important for wall plasters and tile adhesives, where stability on vertical surfaces is crucial for a quality finish.
Crack Prevention: The water retention and flexibility imparted by CMC help minimize the risk of shrinkage and cracking in cement-based products. This is essential for maintaining the structural integrity of the construction material over time, especially in challenging environmental conditions.
Compatibility with Other Additives: CMC is compatible with a wide range of construction additives and can be easily incorporated into various formulations without negatively affecting the properties of other components. This makes it a versatile choice for enhancing performance in different types of construction materials.

n tile adhesives, CMC provides the necessary consistency and adhesion properties, ensuring that tiles adhere securely to walls and floors. It also helps in maintaining the position of tiles during the curing process.
CMC is widely used in cement mortars to improve water retention, workability, and adhesion. It enhances the overall performance of mortars used in bricklaying, rendering, and surface repairs.
Carboxymethyl Cellulose (CMC) can be used with putty powder. CMC improves water retention, workability, and adhesion, ensuring a smooth, crack-resistant finish. It prevents sagging on vertical surfaces, enhances bonding to substrates, and provides a finer texture, resulting in higher quality and more durable putty applications.
CMC contributes to the viscosity and flow properties of self-leveling compounds, ensuring a smooth and even surface. Its water retention ability helps maintain the integrity and strength of the compound as it sets.
In EIFS, CMC enhances the performance of base coats and finishing plasters by providing good workability, adhesion, and resistance to cracking.
CMC is a valuable additive in gypsum plasters, where it helps in improving the workability, consistency, and adhesion of the plaster. It also aids in controlling the setting time and prevents cracking.
Superior Water Retention:
Provides excellent water retention capabilities, ensuring longer open time and improved workability of mortars and plasters.
High Thickening Efficiency:
Enhances the viscosity and consistency of cement-based materials, leading to better application and smoother finishes.
Improved Adhesion:

CMC should be stored in a cool, dry place, away from direct sunlight and moisture. Proper storage conditions help maintain its quality and extend its shelf life, typically up to 2 years under ideal storage conditions.
The choice of CMC grade depends on the application requirements, such as desired viscosity, water retention, and solubility. For example, construction applications typically require high-viscosity CMC for better water retention, while food applications may need food-grade CMC with high purity. Our technical team can assist you in selecting the most suitable grade.
We offer various grades of CMC tailored for different applications, including industrial-grade, food-grade, and construction-grade CMC. Each grade varies in terms of purity, viscosity, and degree of substitution, making them suitable for specific uses like cement additives, food thickening, or pharmaceutical applications.
