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 defoamers
are 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.

APPLICATION of Silicon Emulsion Defoamer Agent :
CALMUSS 204 is self emulsion defoamer type antifoams can be used in variety of industrial application. Silicone Base defoamer function to Antifoams are specially formulated emulsion for general purpose applications. Silicone defoamers are generally preferred for better stability and more lasting defoaming power in very small concentrations. Silicone antifoams find application in various industries.
Silicon Emulsion Defoamer composition is mixture of fatty acid ethexylated and fatty acid esters with neutral carriers. The quantity of antifoam percentage will be dependent upon the application, however, it is recommended that evaluations begin at 100 ppm of the active silicone.
A typical Silicon Emulsion Defoamer dose rate 0.1-0.8% which is water-dilutable. Dosage will vary form the substance of foaming agent, temperature, and pH.
