Application of Hydroxyethyl Methyl Cellulose (HEMC) in Building Materials
As the construction industry continues to pursue higher standards in energy efficiency, workability, and material performance, the choice of key additives has become increasingly important. Recently, we engaged in technical collaboration and product testing with a major building materials company in the Middle East, focusing on the application of Hydroxyethyl Methyl Cellulose (HEMC) in dry-mix mortars. The results were highly positive.
Customer Background and Requirements
The customer is a well-known manufacturer of tile adhesives, putties, and dry-mix mortars, serving both residential and commercial construction sectors. Due to the region’s hot and dry climate, the customer placed strong emphasis on water retention, smooth workability, and final film quality of their mortar products.
Their previously used cellulose ether presented several challenges:
Unstable water retention under high-temperature working conditions
Poor spreading smoothness, causing visible tool marks
Slight whitening and cracking after drying
Incompatibility issues in more complex formulations
They aimed to upgrade their HEMC additive to improve formulation performance and ensure consistent application quality.
Our Approach and Product Performance
Based on their local conditions and formulation needs, we recommended our proprietary high-viscosity Hydroxyethyl Methyl Cellulose (HEMC) . This product offers excellent dissolving behavior and formulation adaptability, enhancing water retention while also improving application texture and film integrity.
We provided comprehensive technical documentation and adjustment advice for their formulas, and supported a full round of testing. The key outcomes included:
Significantly improved water retention, even at 45°C, effectively preventing premature drying or cracking
Smoother workability, allowing easier troweling and cleaner finishes
Tighter, cleaner film formation, with no whitening or peeling, delivering better visual performance
High compatibility, working seamlessly with existing additives such as redispersible powders and waterproofing agents
After several rounds of testing, the customer adopted Hydroxyethyl Methyl Cellulose (HEMC) into their primary tile adhesive and wall putty products. Post-launch feedback confirmed product consistency and improved customer satisfaction.
The Value Delivered
Although this customer was not previously a long-term partner, they quickly recognized our technical responsiveness, product suitability, and professional communication throughout the process.
By understanding their formulation challenges and climate-related constraints, we helped them optimize product performance and reduce the risk of on-site issues—ultimately strengthening their competitive position in the market.
Conclusion
Hydroxyethyl Methyl Cellulose (HEMC) is a critical additive in dry-mix building materials, and its quality directly impacts application results. We remain committed to delivering reliable product quality and flexible formulation support to help our global partners innovate and enhance building material performance.
