- Applications
- When used in a white base paint, the starting recommendation for dosage is 0.2% based on the total weight of the paint.
- Recommendation is to add the Berol 185 in the grind, as to facilitate an improved wetting and distribution of the various surface active ingredients on the pigments.
- For enhanced color acceptance, Berol 185 works especially well in formulations based on anionic stabilized systems.

Technical Details & Test Data
- Surfactants in Paint
- The paint is from a surface chemistry point of view a very complex system. In order to make all these components form a stable colloidal suspension, a ‘compatibilizer’ is often required.
- The use of a surfactant as compatibilizer facilitates the use of having multiple sourcing of polymer emulsions, colorants / pigments and rheology modifiers, as the surfactants and surface chemistry properties of these components usually differ between producers.
- In the formulation of water borne paints, nonionic surfactants are often preferred. One main reason is that their action is less impacted by the presence of salts and other electrolytes, as are anionic surfactants.
- An Efficient Compatibilizer
Berol 185 is a nonionic, readily biodegradable surfactant that offers improved surface wetting, paint stability and color acceptance properties in water borne paints. It is a non label product, easy to handle and with good foam control.

Wetting performance
Berol 185 is a very efficient wetter and less dosage is needed to wet pigments compared to other wetting agents.
