Hydroxyethyl cellulose (HEC) is a natural polymer material cellulose as raw material. Non-ionic cellulose ether made by a series of chemical processing. It is an odorless, tasteless and non-toxic white to off-white powder or granule. It can be dissolved in cold water to form a transparent, viscous solution. It has thickening. Adhesion, dispersion, emulsification, film formation, suspension, adsorption, surface activity, salt resistance, moisture retention and protective colloid. HEC can be used in construction materials, coating industry, petrochemical industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, cosmetics, tobacco, ink, papermaking and other industries.
Important properties:
1. HEC soluble cold or hot water, no precipitation under high temperature or boiling. This gives it a wide range of solubility and viscosity characteristics. That is non-thermogel proprety.
2. Non-ionic type can coexist with a wide range of other water-soluble polymers, surfactants and salts. It is an excellent colloidal thickener containing a high concentration of electrolyte solution.
3. It has twice the water retention capacity than methyl cellulose. It has good flow regulation.
4. The product is stable and mildew proof. And make the coating have a better can open reaction, and have good leveling performance during construction.
Application:
1. For water-based latex coatings: It can significantly improve thickening and leveling performance.
2. For Oil drilling: It can improve mud carrying capacity during drilling, and prevent a large amount of water from entering the oil layer from the mud, and stabilize the oil layer production capacity.
3. For building construction and building materials: HEC is an effective thickener and binder for cement slurry and mortar. It can improve the fluidity and construction performance of the mortar, and prolong the water evaporation time, and increase the initial cracks of the concrete. It used for painting gypsum, bonding gypsum, gypsum putty can significantly improve its water retention and bonding strength.
4. For toothpaste: HEC can guarantee the stability of toothpaste paste due to its strong salt resistance and acid resistance. In addition, the toothpaste is not easy to dry due to its high water retention and emulsifying ability.
5. For water-based ink, HEC can make the ink dry quickly and not penetrate.
6.HEC is widely used in textile printing and dyeing, papermaking, and daily chemicals.
