Foam Control Agent | Silicon Defoamer Chemical :Foam produced during system mixing and application often produces undesirable surface defects and negatively impacts performance. These new multifunctional products provide excellent foam control and wetting, thus minimizing defects, such as fisheyes and craters, commonly caused by other defoamers.

Defoamers Molecular defoamersare surface-active agents that break foam at the molecular level rather than through incompatibility. Typically, foam causing components stabilize foam because of ionic forces, hydrogen bonding and van der Waals forces. In aqueous systems, molecular defoamers function to destabilize the foam lamella by disrupting these forces, thus causing the foam to collapse. When absorbed at the foam interface, molecular defoamers reduce surface elasticity of bubbles to prevent stabilization. They also reduce surface viscosity of the foam lamella and increase the liquid drainage rate. These combined effects further enhance the defoaming ability of molecular defoamers.
