Cellulose is predominantly found in plants, particularly in hard-to-digest parts such as wood, cotton, and the leaves of many plant species. It is also a significant component of agricultural byproducts like straw and corn stalks. Interestingly, cellulose is not only present in the plant kingdom; some marine organisms and bacteria also produce cellulose, although in smaller quantities.

As a modified cellulose, HPMC has excellent thickening, bonding and water retention properties. When added to mortar, it can significantly improve the operability of the mortar, extend the construction time, reduce vertical slippage, and provide better working conditions for construction workers. In addition, the use of HPMC can effectively reduce the evaporation of water during the construction process of the mortar and improve the strength and durability of the mortar.

In recent years, there has been an increased focus on sustainability and environmental impact in the construction industry. RDPs are often considered eco-friendly alternatives to traditional adhesive systems. Their formulation can be designed to reduce volatile organic compound (VOC) emissions, contributing to healthier indoor air quality.
