Defoamers/Deaerators are chemical additives that reduce and prevent the formation of foam.  The selection and consideration of usage of defoamers mainly is related to systems; from the processing and to its final application.  High viscosity (build) systems are harder to defoam and need stronger defoamers/deaerators.
