Chemical stability is a necessary condition for defoamers, so defoamers in foaming systems generally do not fail due to chemical reactions. Most of the reasons for their failure are caused by changes in the dispersion state. Only by eliminating this cause can the effectiveness of the defoamer be fully exerted. 1. The defoamer particles have.. read more →

Causes of foam formation Water-based paints are not pure liquids; they are colloidal dispersions of particles (pigments, resins) in a carrier (water). One of the key factors in the stability of air bubbles in paints is surfactants, as it is they that hold all the different ingredients together and prevent them from separating or settling… read more →
