Abstract

PURPOSE: To obtain a defoaming agent having an excellent suppressing effect on foaming caused by an organic solvent especially an organic solvent soln. contg. a water- and oil-repellent agent by using a perfluoropolyether compd.
CONSTITUTION: A perfluoropolyether compd. expressed by the formula in an irregular coupling order is used as an effective component. The compd. is obtained by fluorinating polyether contg. a peroxy group, and also sold on the market. Althought the compd. can be added directly to the object to be defoamed when used as a defoaming agent, the compd. is generally dissolved in an organic solvent to obtain a 5W50% concn. soln., and used. The compd. can also be used jointly with other defoaming agents. The amt. to be added is preferably regulated to about 0.001W30wt%.
