Defoaming
A defoamer droplet enters the thin wall of a bubble, spreads faster than the surfactant can repair it, and the bubble breaks. Air escapes before the film dries.

The science
How our additives work.
Wetting and dispersing
The additive wets each pigment particle and anchors to it, keeping particles apart. Colour strength, gloss and stability develop fully.
Wetting and dispersing agents ›Surface control
The additive moves to the film surface and evens out surface tension, so the coating wets the substrate, flows out and stays free of craters.
Surface control ›Applications
Built for the products you make.
