AFCONA 4008 is a polymeric dispersant used for the deflocculation of pigments. AFCONA 4008 is a polymeric dispersant used primarily in systems where aromatic solvents are forbidden. Compared to other AFCONA PU-grade dispersants, the viscosity reduction effect of AFCONA 4008 is not as strong (this is due to its more polar structure). However, this is not necessary a disadvantage, because not all mill bases require viscosity reduction.

Product Properties

AFCONA 4008 is a polymeric dispersant used primarily in systems where aromatic solvents are forbidden. Compared to other AFCONA PU grade dispersants, the viscosity reduction effect of AFCONA 4008 is not as strong (this is due to its more polar structure). However, this is not necessary a disadvantage, because not all mill bases require viscosity reduction. The special properties and recommended systems for AFCONA 4008 include:

  • Due to its combination of price and performance, AFCONA 4008 is a very attractive product to substitute for conventional wetting and dispersing agents in all kinds of coating systems
  • AFCONA 4008 may be post-added to  correct flooding and floating in all solvent - based paints. It also prevents flooding and  floating when used in mill bases as a co - grinding dispersant. 
  • Pigment concentrates based on AFCONA 4008 give very unique properties like very wide compatibility and lower cost

Note: AFCONA 4008 will become slightly hazy at temperatures of 5°C and below, but this will not influence the performance of the product.

Applications & Uses

Application Details

Addition and Dosage : Add AFCONA 4008 according to the dosages listed below, which should be calculated based on the percent of active ingredient in the dispersant and the weight of pigment in the formula:

  • TiO2 : 2 – 3%
  • Other inorganic pigments : 2 – 5%
  • Organic pigments : 20 – 40%
  • Carbon blacks : 20 – 50%

Incorporation : AFCONA 4008 should be incorporated in the mill base before adding pigments.

Application Details
  • Addition and Dosage
    • 0.5 - 2.0% on total formulation. In general, under normal conditions, the dosage is 0.5 - 0.8% based on total formulation.
  • Incorporation
    • AFCONA 3770 should be added at the end of the batch preparation.
