Product Features
  • Afcona-5251 is a dispersant developed for dispersing and stabilizing transparent iron oxide pigments. Proper use of this product results in:
    • Optimum transparency
    • Higher color strength
    • Flocculation stability
    • Lower viscosity
  • Afcona-5251 may also be used as a dispersant for other inorganic pigments and extenders, for which it reduces the viscosity in the dispersion. Therefore, it is very useful in highly filled systems.
  • Afcona-5251 differs from Afcona-5051 because it is solvent-free. This makes this product very suitable in solvent-free or high solid applications.

Product Applications

Afcona-5251 is recommended for manufacturing resin-free or resin-containing transparent iron oxide pigment concentrates for decorative as well as industrial paints. Very stable concentrates up to 40% may be formulated with this product.

Note: Afcona – 5251 will become slightly hazy at temperatures below 5° C. This will not influence the performance of the product.

Addition and Dosage

Calculation method for the required amount of active ingredient on pigment:

Transparent iron Oxides 10 – 20%
TiO2 2 - 3%
Other inorganic pigments 2 - 4%

 

Incorporation

Afcona-5251 should be incorporated in the mill base before adding the pigments.
