Properties and Precautions of Hydroxyethyl Cellulose
Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdery solid, which is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin). Nonionic soluble cellulose ethers. In addition to thickening, suspending, binding, floati...Read more -
Introduction of compounding technology of hydroxypropyl methylcellulose HPMC
Hydroxypropyl methylcellulose HPMC compounding technology is a technology that uses HPMC as the main raw material and adds other specific additives in a certain proportion to prepare modified hydroxypropyl methylcellulose HPMC. HPMC has a wide range of uses, but each application has different spe...Read more -
Method for using hydroxypropyl methylcellulose and method for preparing solution
How to use hydroxypropyl methylcellulose: Add directly to production, this method is the easiest and the shortest time-consuming method, the specific steps are as follows: 1. Add a certain amount of boiling water (hydroxyethyl cellulose products are soluble in cold water, so you can add cold wate...Read more -
Comparison of the types and advantages and disadvantages of thickeners in water-based paints!
Coating additives are used in a small amount in coatings, but they can significantly improve the performance of coatings, and have become an indispensable part of coatings. Thickener is a kind of rheological additive, which can not only thicken the coating and prevent sagging during construction,...Read more -
The five “agents” of water-based coatings!
summary 1. Wetting and dispersing agent 2. Defoamer 3. Thickener 4. Film-forming additives 5. Other additives Wetting and dispersing agent Water-based coatings use water as a solvent or dispersion medium, and water has a large dielectric constant, so water-based coatings are mainly stabilized by ...Read more -
Application of Hydroxyethyl Cellulose (HEC) in Latex Paint
Thickeners for latex paints must have good compatibility with latex polymer compounds, otherwise there will be a small amount of texture in the coating film, and irreversible particle aggregation will occur, resulting in a decrease in viscosity and coarser particle size. Thickeners will change th...Read more -
What is the role of hydroxyethyl cellulose in coatings!
What is Hydroxyethyl Cellulose? Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin), belongs to Nonionic soluble cellulose ethers. Since HEC has good pro...Read more -
How should the thickener in water-based paint be added?
Today we will focus on how to add specific types of thickeners. The types of commonly used thickeners are mainly inorganic, cellulose, acrylic, and polyurethane. Inorganic Inorganic materials are mainly bentonite, fumed silicon, etc., which are generally added to the slurry for grinding, because ...Read more -
