Abstract:
Disclosed is a defoaming composition. The defoaming composition is composed of composition E and composition F. The composition E is composed of a hydrogen bond donor, polyether modified polysiloxane C, and a hydrogen bond acceptor X. The composition F is composed of a hydrogen bond donor, fatty alcohol polyether D, and a hydrogen bond acceptor Y. The polyether modified polysiloxane C is composed of polyorganosiloxane A and allyl polyether B.
