4.0 - 8.0 %
Recommendation for Use
  • We generally recommend adding 4.0 - 8.0 % VARIPHOB® AC 2530 in aqueous coating systems related to the total formulation.
  • The optimal dosage has to be determined in pre-trials.
  • The product is typically considered a binder when calculating the pigment volume concentration due to its crosslinking character.
  • In aqueous coating systems the product is added during or at the end of the production process.
Application Technique
  • VARIPHOB® AC 2530 is especially recommended for pigmented formulations.
  • Preferred Application Fields:
    • Dispersion paints and plasters
    • Silicate paints and plasters
    • Silicone resin paints and plasters
