One of the main uses of HPMC in construction is as a binder in cement-based materials. HPMC improves the workability and cohesion of cement mixtures, making them easier to handle and apply. It also helps to reduce water loss during the setting process, resulting in stronger and more durable structures. Additionally, HPMC enhances the adhesion of cement to various substrates, such as bricks, tiles, and stones, improving the overall performance of the material.

Hydroxypropyl methylcellulose, a cellulose derivative, is synthesized through an alkali treatment of cellulose followed by etherification with propylene oxide and methyl chloride. The molecular weight of 200,000 in HPMC signifies a high degree of polymerization, which significantly influences its physical and chemical characteristics. This high molecular weight imparts superior viscosity, stability, and film-forming abilities to the substance.
