  • In repair mortars, HPMC enhances the compatibility with existing materials and provides necessary flexural strength, making the repairs durable and less prone to failure. Moreover, as sustainable building practices become increasingly important, the ability of HPMC to improve the performance of eco-friendly binders will contribute to its growing popularity.


  • The Food and Drug Administration (FDA) includes Ethylcellulose, Hydroxypropylcellulose, Methyl Ethylcellulose and Hydroxypropyl Methylcellulose on its list of multipurpose additives allowed to be directly added to food. FDA also permits Cellulose and a number of modified cellulose polymers to be used as indirect food additives. For example, Cellulose, Cellulose Acetate Butryate, Cellulose Acetate Propionate, Cellulose Gum, Hydroxyethylcellulose, Hydroxyethyl Ethylcellulose, Hydroxypropyl Methylcellulose and Methylcellulose can be used in adhesives in contact with food. As substances migrating to food from paper and paperboard products, FDA considers Cellulose Acetate and Ethylcellulose to be Generally Recognized as Safe (GRAS). The FDA has also approved the use of Cellulose Gum, Hydroxyethylcellulose, Hydroxypropyl Methylcellulose and Methylcellulose for use as ophthalmic demulcents in over-the-counter (OTC) drug products for the eyes.

  • Cellulose-derived HPMC is a polymer that readily dissolves in water, a natural polymer found in plant cell walls. It is produced by treating cellulose with a combination of alkali and etherification agents, which results in the substitution of hydroxyl groups with methyl and hydroxypropyl groups. This modification improves the solubility and other physical properties of cellulose, making it suitable for various applications.

  • In the tile adhesive market, for example, RDP allows for the creation of formulations that provide excellent grip and flexibility, suitable for both wall and floor applications. When used in dry mortars, RDP results in improved performance characteristics such as better water retention, enhanced bonding, and superior workability.
