  • Reduces the tendency of pigment settling in silicate emulsion paints.
  • Susceptible to frost.

Applications & Uses

Coating Type
Mode of Action

The application of Betolin AH 250 results in a hydrophobic surface of paint or plaster coats; thus the water uptake (w24 value) is strongly reduced. The water vapor permeability (sd value) is not influenced.

Applications

Betolin AH 250 is added as water repellent to waterbased coatings, especially also to silicate emulsion paints and plasters. Usual concentrations are 0,6 – 1,0 up to 2,0 weight %.
