General Description
DF-977 is a high efficiency defoamer with a very broad spectrum of applications. DF-977 is largely chemically inert, hence it will not normally interfere with chemical process. DF-977 will not impair the wetting action of defoamed surfactants and since it is added in small quantities, will not lower product efficacy. DF-977 is very effective when used to control foaming conditions often found in Glycol Dehydration and Amine Sweetening processes as well as municipal waste water systems.
Application
GT-977 is extensively used in a wide variety of industrial batch processing applications, wherever foams create intense problem especially where aqueous systems are followed such as in Paper Industry, Petroleum Refining, Textile Processing, fermentation processes, etc.DF-977 is readily soluble in water, glycol or amine and can be either continuously injected or batch treated at rates of 50-500 ppm. Metering is recommended to prevent over treatment.
