PC-1244 Defoamer is a solution of organic polymer in a petroleum solvent. It enhances air release properties and prevents foam formation in acidic or neutral organic fluids at temperatures up to 400 °F. It also performs in some alkaline systems. It has demonstrated an ability to retain its defoaming capacity over extended periods of time. It works without materially affecting the surface tension of the media. PC-1244 contains no silicone. PC-1244 Defoamer applications include usage in gear oils, specialty lubricants, and hydraulic, turbine and transmission oils.
