Silicone-based defoamers. Silicone-based defoamers are polymers with silicon backbones. These might be delivered as an oil or a water-based emulsion.
Used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols.
Antifoam agents are chemicals used in a variety of industrial processes, such as those in the oil and gas industry, to regulate and prevent the development of foam. Drilling, well stimulation, and transporting crude oil and natural gas are just a few of the procedures in the oil and gas production process where foam formation can occur.
Additive is a liquid defoaming agent formulated with higher esters to control foaming in all water-base drilling fluids containing freshwater, brackish water, seawater, saltwater, and saturated saltwater, as well as completion fluids
