Defoamer composition for suppressing oil-based and water-based foams |
摘要 |
Defoamer compositions effective for the suppression of oil-based and water-based foams. The defoamer compositions comprise a fumed metal oxide, such as fumed silica, or another silica-based material dispersed in an organic solvent. The fumed metal oxide of silica-based material is preferably present at a low weight percentage and may be coated with polydimethylsiloxane ("PDMS"). The defoamer composition may also include one or more traditional defoamer compositions.
