What is the difference between HPMC and MC
MC is methyl cellulose, which is obtained by treating refined cotton with alkali, using methyl chloride as an etherifying agent, and making cellulose ether through a series of reactions. Generally, the degree of substitution is 1.6~2.0, and the solubility is also different with different degrees ...Read more -
Factors Affecting the Viscosity Production of HPMC
1. Viscosity Control High-viscosity hydroxypropyl methylcellulose cannot produce very high cellulose only by vacuuming and replacing with nitrogen. However, if a trace oxygen measuring instrument can be installed in the kettle, the production of viscosity can be controlled artificially. 2. Use of...Read more -
The most concise water-based paint thickening technology tutorial
1. Definition and function of thickener Additives that can significantly increase the viscosity of water-based paints are called thickeners. Thickeners play an important role in the production, storage and construction of coatings. The main function of the thickener is to increase the viscosity o...Read more -

HPMC application in building materials
Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. Has the pro...Read more -
HPMC classification and dissolution method
1.Classification: HPMC can be divided into instant type and hot-melt type. Instant-type products disperse quickly in cold water and disappear into the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and has no real dissolution. After about 2 minutes, the ...Read more -
Main uses and differences of HPMC HEC 01. Hydroxyethyl Cellulose
01. Hydroxyethyl Cellulose As a non-ionic surfactant, hydroxyethyl cellulose not only has the functions of suspending, thickening, dispersing, flotation, bonding, film-forming, water retention and providing protective colloid, but also has the following properties: 1. HEC is soluble in hot or c...Read more -

The main raw material of HPMC is as bellow: Refined cotton, methyl chloride, propylene oxide, other raw materials, caustic soda, acid, toluene, isopropanol, etc. What is the key effect of hydroxypropyl methylcellulose in putty powder, and whether organic chemistry occurs? HPMC plays three functio...Read more -
The Encounter of Hydroxyethyl Cellulose and Water-Based Coatings
What is hydroxyethyl cellulose? Hydroxyethyl cellulose (HEC), a white or pale yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chlorohydrin), belonging to the genus Nonionic soluble cellulose ethers. Because HEC has good...Read more -
Common construction problems and solutions for exterior wall coatings!
01 Slow dry and stick back After the paint is brushed, the paint film does not dry for more than the specified time, which is called slow drying. If the paint film has been formed, but there is still a sticky finger phenomenon, it is called back sticking. Causes: 1. The paint film applied by br...Read more -
