Building gypsum is well known for its excellent performance and is widely used in construction materials. It is commonly applied in dry-mixed mortar systems such as masonry mortar, finishing plaster, gypsum-based decorative mortar, and gypsum-based joint fillers.
HUA CHEMICAL is specialized in the production and development of chemical additive solutions for construction materials. In gypsum-based applications, our cellulose ether products, including Hydroxypropyl Methyl Cellulose (HPMC) and Hydroxyethyl Methyl Cellulose (HEMC), function as key additives for water retention, thickening, and lubrication, while also providing a certain retarding effect to improve open time and workability. In addition, Redispersible Polymer Powder (RDP) plays an important role in enhancing adhesion, flexibility, and mechanical strength of gypsum systems. The combination of cellulose ether and RDP effectively improves construction performance, reduces shrinkage and cracking, prevents hollowing, and ensures stable early strength and long-term durability of gypsum-based products.
