The core active ingredient of Defoamer King FAG470 is polyether-modified polysiloxane, a modified organosilicon polymer formed by grafting polyether chains onto the polysiloxane backbone through chemical methods. Its unique molecular structure design gives the product both strong defoaming ability of organosilicon and excellent water dispersibility of polyether, solving the problem of difficult dispersion of traditional organosilicon defoamers in water.
The product is supplied in aqueous emulsion form, with active components stably dispersed in the aqueous medium. The non-ionic formulation enables instant dispersion in water without strong agitation, allowing uniform distribution in the foaming system. Based on the characteristics of this ingredient, Defoamer King FAG470 maintains chemical structure stability under harsh conditions such as high temperature and strong alkalinity, and is not prone to demulsification or failure.
It should be noted that, as a mature industrial formulated product, in addition to the core active ingredient polyether-modified polysiloxane and the aqueous dispersion medium, the product also contains necessary auxiliary components such as emulsifiers and stabilizers to ensure long-term storage stability and ease of use. The types and proportions of specific auxiliary components are within the scope of product formula confidentiality, and there is currently no CAS number record for this product in the database.

Thanks to the unique molecular structure of polyether-modified polysiloxane, Defoamer King FAG470 is particularly suitable for high temperature and strong alkali conditions, such as scouring, bleaching, and dyeing in textile printing and dyeing where high temperature alkaline baths are used; it is also applicable to fields requiring rapid defoaming and lasting foam suppression, such as water treatment, metalworking fluids, and industrial cleaning. Its non-ionic characteristics provide good compatibility with various anionic and cationic auxiliaries, making it less prone to adverse reactions.
