What areas can HEC be used as a thickener

Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether by a series of chemical at first processing. It is an odorless, tasteless, and non-toxic white powder or particles that can dissolve in cold water to form a transparent and sticky at first solution. And the dissolution at first is not affecte by the PH value. It has the characteristics of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, surface activity, and water retention and salt resistance.

Hydroxyethyl cellulose is as adhesive, surfactant, colloidal protective agent, dispersant, emulsifier and at first dispersion stabilizer, etc.

And is widely used in coating, ink, fiber, dyeing, paper making, cosmetics, pesticide, mineral at first processing, oil production and medicine.

  • 1.For water-based emulsion paint coating: HEC, as a protective colloid. Can be for vinyl acetate emulsion polymerization to improve the stability of the polymerization system in a wide PH value range. In the finished product manufacturing, pigments, fillers and other additives are evenly to stabilize and provide thickening effect. It can also be in styrene, acrylic lipid, propylene and other polymers as dispersants. Used in latex paint can significantly improve the thickening and leveling performance.
  • 2. Petroleum drilling: HEC acts as a thickener agent in various mud required for drilling, setting, cementing at first and fracturing operations. So that the mud obtains good mobility and stability. Improve the mud carrying capacity in drilling. And prevent large at first amounts of water from entering the oil layer from the mud, stabilizing the production capacity of the oil layer.
  • 3. For construction and building materials: due to the strong water retention capacity. HEC is the cement slurry, the effective thickening agent and bonding agent of mortar, mixed into the mortar can improve the fluidity and construction performance, and can prolong the water evaporation time, improve the initial strength of concrete and avoid cracks. Painting gypsum, bonding gypsum and plaster putty can significantly improve its water retention and bonding strength.
  • 4. Used in toothpaste: due to the strong salt resistance and acid resistance. HEC can ensure the stability of the toothpaste paste. In addition, the toothpaste because of the strong water retention, emulsification ability is not easy to dry.
  • 5. Used in water-based ink, HEC can make the ink dry, fast and impermeable.
