Alkaterge-E in Coatings

In paints and ink, its main function as a co-dispersant is to achieve a superior dispersion and wetting of pigment. It can address the problem of severe flocculation in paints by providing good dispersion. Alkaterge-E also works well with most other dispersants. There are many advantages of using Alkaterge-E as co-dispersant:

  1. Enhances pigment dispersion level
  2. Grinding time reduction
  3. Preventing gelation of coating and inks
  4. Works both in water and solvent paint system

However, Alkaterge-E cannot be used as a sole dispersant. It reduces the dosage of the dispersant which can be very expensive and may reduce formulation cost. The ratio of dispersant to Alkaterge-E can be 4:1 or 2:1. Add 25-50% Alkaterge-E to dispersant. This is the optimal dosage that will give the same performance.

Other Use of Alkaterge-E

Alkaterge-E can also be used in the following application:

  • Salts and Soaps
  • Paper, Textiles and Metal Cleaners
  • Emulsion Stabilizer
  • Acid Acceptor
  • Antifoam Agent
  • Antioxidant
