This is not just another defoamer! SI-O-KWEL® antifoam agents are specially compounded to stop foam quickly, effectively and economically. In chemical, textile, food, petroleum and other industries. These products show high uniformity and stability. All but SS-201 meet FDA requirements for food usage.

To prove the effectiveness of SI-O-KWEL, we would like to send you a sample to check in your operation—exactly where the foam occurs. Just complete the coupon. Stauffer Chemical Company, Silicone Division, 380 Madison Avenue, New York, N.Y. 10017.
