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
DF-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.
