| 摘要 |
The present invention relates to an antifoaming preparation for aqueous systems consisting essentially of a water insoluble organic liquid, e.g., mineral oil; a filler; a hydroxyl endblocked organopolysiloxane or a benzene soluble organopolysiloxane resin; and an ingredient, e.g., KOH, a hydrocarbon amine, ammonia, or hexamethyldisilazane which would lend compatibility between the filler and the silicone fluid or silicone resin component. The preparations in question would be particularly useful in the pulp and paper industry. |
