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 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 -

What should be paid attention to in the configuration of sodium carboxymethyl cellulose CMC
Basic properties of sodium carboxymethyl cellulose CMC Most of the cmc is high-quality pseudoplastic, and some production varieties are almost solid and gelatinous, and vigorous stirring can make it watery. Carboxymethyl cellulose often exhibits pseudoplastic behavior, or shear thinning. Such tra...Read more -
What should be paid attention to in the configuration of sodium carboxymethyl cellulose
In the process of configuring sodium carboxymethyl cellulose, our usual practice is relatively simple, but there are several that cannot be configured together. First of all, it is strong acid and strong alkali. If this solution is mixed with sodium carboxymethyl cellulose, it will cause fundamen...Read more -
How to make CMC Sodium Carboxymethyl Cellulose?
Sodium carboxymethyl cellulose (CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, and is the most important ionic cellulose gum. CMC is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid. The mol...Read more -
