Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used 

Low viscosity: 400  is mainly used for self-leveling mortar.  Reason: low viscosity, good leveling,  high mortar density.  

Medium and low viscosity: 20000-40000 Medium viscosity: 75000-100000  

High viscosity: 150000-200000  mainly used for mortar  Reason: high viscosity, the mortar is not easy to fall off, sag, and improve workalibity.

1. What is the main application of hydroxypropyl methylcellulose (HPMC) ? 

——Answer: HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. At present, most HPMC is construction grade. In construction grade, putty powder is used in a large amount, about 90% is used for putty powder, and the rest is used for cement mortar and glue.

 2. What are the types of HPMC, and what are the differences?

 ——Answer: HPMC can be divided into instant type and hot-melt type. The instant type products are quickly dispersed in cold water and disappear in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water without real dissolution. About 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid. Hot-melt products, when they come together in cold water, they can quickly disperse in hot water and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until a transparent viscous colloid is formed. Hot-melt type can only be used in putty powder and mortar. In liquid glue and paint, clumping occurs and cannot be used. The instant type has a wider range of applications. It can be used in putty powder and mortar, as well as in liquid glue and paint. There is no contraindication.
