Cellulose ethers are essential additives in cement-based products, widely used in the construction industry for applications like tile adhesives, mortars, and plasters. These compounds, primarily including Hydroxypropyl Methylcellulose (HPMC), and Hydroxyethyl Methylcellulose (HEMC), play a crucial role in influencing the performance of cement formulations. To achieve optimal results, it’s important to understand and control the factors that affect how these cellulose ethers behave in such mixtures.
