SAG 638 antifoam emulsion is an excellent candidate to consider for general purpose foam control in aqueous systems.
SAG 638 antifoam emulsion excels in applications requiring excellent knock down and durability. Remarkably small concentrations can sharply reduce the foam created, which can cut down the processing time and potentially permit maximum capacity production.
| Key Features and Typical Benefits outstanding and quick foam knockdown excellent durability in both non-ionicand anionic surfactant systems long lasting antifoam performance inacidic and alkaline conditions good emulsion stability readily dispersible in the foaming media
| Potential Applications foam control in textile pre-treatment processes and textile print pastes textile sizing and scouring agents acrylic latexes and thickeners used for textiles and nonwovens other chemicals and chemical processes requiring foam control |

General Instructions for Use
SAG 638 antifoam emulsion can provide excellent performance as a defoamer as well as an antifoam agent. Therefore, it is recommended that SAG 638 antifoam emulsion be added to the aqueous system before the foaming process
starts.
Generally, only a very low concentration of 50 - 100 ppm or 0.05 - 0.1 g/L of SAG 638 antifoam emulsion is necessary to suppress foam. However, the optimum level is really dependent upon many factors such as temperature, bath composition,
viscosity or agitation of the foaming system.
Use SAG 638 antifoam emulsion as received or dilute first with water.
Mix the antifoam well before use.
Dilution: Mix 3 to 10 parts of water to 1 part antifoam emulsion and stir gently until a uniform mixture is obtained. For a long-
term bulk stability of the dilution, thickener and biocides need to be added.
