Hydroxypropyl methylcellulose mainly plays the role of water retention and thickening in cement mortar and gypsum based slurry, and can effectively improve the adhesion and sag resistance of slurry.

What is the main function of the application of hydroxypropyl methyl cellulose in putty powder? Is there a chemical reaction?

In recent years, with the continuous development of external wall insulation technology, the continuous progress of cellulose production technology, and the excellent characteristics of HP cellulose itself, HP cellulose has been widely used in the construction industry.

(1) The effect of the fresh mortar: ① Prolong the working time and adjustable time; ② Improve the water retention performance to ensure the hydration of cement; ③ Improve sag resistance (special modified polymer powder); (4) improve the workability (easy to construct on the base material, easy to press the ceramic tile into the adhesive).

Tile adhesives are compounds used to stick tiles to walls or floors firmly. Tile adhesive is expected to fix the tiles not just for several years but for decades without failure. Therefore, it must be easy to use and should not have any gaps between the tile and the substrate.

According to the application, Hydroxypropyl Methyl Cellulose (HPMC) can be divided into construction grade, food-grade, and medical grade. In construction, HPMC is mainly used in putty powder, accounting for 90% of the total.

The construction industry has experienced massive growth in incorporating new materials to enhance the output and overall performance of construction products. Among such trendy innovations is the gypsum plaster.

Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to determine the viscosity of HPMC. The main methods are HaakeRotovisko, Hoppler, Ubbelohde and Brookfield.
