One of the most common applications of HPMC ether is in the construction industry. It is used in cement-based materials such as mortars, renders, and grouts to improve workability, water retention, adhesion, and durability. HPMC ether acts as a thickening agent that helps to prevent the segregation of particles and improve the overall performance of the material. It also enhances the consistency and stability of the mixture, making it easier to apply and reducing the likelihood of cracks or shrinkage.
