Hydroxyethyl cellulose to make water-based paint (1) Because the surface-treated hydroxyethyl cellulose is powdery or fibrous solid. When preparing hydroxyethyl cellulose mother liquor, remind you to pay attention to the following points: (1) Before and after adding hydroxyethyl cellulose, keep stirring until the solution is completely transparent and clear. (2) Slowly sieve into the mixing
Hydroxyethyl cellulose to make water-based paint (2) 1. Add directly during production - this method is simpler and takes less time. Add directly when grinding the pigment: This method is simple and takes a short time. The detailed steps are as follows: (1) Add appropriate purified water into the large bucket of the high-shear mixer
HEC(Hydroxyethyl cellulose) is used as an additive in various aspects. This article briefly introduces the main characteristics of HEC. Thickening Hydroxyethyl cellulose (HEC) is an ideal thickener for paints and cosmetics. In practical application, the combination of its thickening property, suspending property, safety, dispersibility and water retention will produce more ideal effect. Pseudoplasticity Pseudoplasticity is
What is Hydroxyethyl Cellulose Hydroxyethyl cellulose (HEC) is an important hydroxyalkyl cellulose. It was successfully prepared by Hubert in 1920. And it is also a water-soluble cellulose ether with a large production volume in the world. It is an important cellulose ether with the largest output and rapid development after CMC and HPMC. At present,
In this article we introduce HEC in the Coating Industry. Hydroxyethyl cellulose (HEC) is a white or light yellow, odourless, non-toxic fibrous or powdered solid. Prepared by etherification of basic cellulose and ethylene oxide (or chloroethanol), a non-ionic soluble cellulose ether. Due to its good thickening, suspending, dispersing, emulsifying, bonding, film forming, moisture protection and
Following the previous article, we continue to introduce HEC and CMC in the classification of cellulose ethers. 1.1.3 Hydroxyethyl cellulose (HEC) It is made from refined cotton treated with alkali and reacted with ethylene oxide as etherizing agent in the presence of acetone. Its substitution degree is generally 1.5~2.0. It has strong hydrophilicity and is
