INTRODUCTION It is well known that conventional silicone foam control agents used in the papers, textiles, metal working, coating and adhesion processes, cause many disadvantage results. Especially in the textile jet dyeing, due to the high temp (120-130oC) and shear conditions, silicone oil always plating out on the inside of dye bath and cause severe spot and shading problem on the textiles. Now the new compounds ANTIFOAM AF-1300 has been found and designed for used in almost of the foam control case without introducing spots and other problems. TYPICAL PROPERTIES Appearance .....................................................................Opaque Liquid Specific Gravity 25oC .....................................................1.01 0.03 Activity Content .............................................................100% Stability........................................................................... Excellent APPLICATIONS ANTIFOAM AF-1300 is often added to the processing system before foaming start as foam inhibitor. Although effective concentration vary with each foaming system. ANTIFOAM AF-1300 is effective in the concentration as low as 50 ppm. It must be noted that ANTIFOAM AF-1300 reaches maximum antifoam efficiency over 45oC. So the optimum foam control in foaming systems must over 45oC.
