DEFOAMING AGENT
The object of the present invention is to provide a defoaming agent that is superior in defoamabilities (initial defoamability and defoaming durability). The present invention is a defoaming agent comprising a bisamide (A) in dispersion in a polyether compound (B), wherein the content of the bisamid...

| description | The object of the present invention is to provide a defoaming agent that is superior in defoamabilities (initial defoamability and defoaming durability). The present invention is a defoaming agent comprising a bisamide (A) in dispersion in a polyether compound (B), wherein the content of the bisamide (A) is 0.01 to 10% by weight and the content of the polyether compound (B) is 90 to 99.99% by weight based the weight of the bisamide (A) and the polyether compound (B), and the mode (µm) in the particle diameter distribution on a volume basis of the bisamide (A) is 0.1 to 5 µm. The bisamide (A) is preferably a bisamide represented by formula (1),
R 1 -CONH(CH 2 ) t -NHCOR 1 (1)
wherein R 1 is an alkyl group, an alkenyl group, a hydroxyalkyl group or a hydroxyalkenyl group having 10 to 22 carbon atoms, and t is an integer of 1. to 6. |
