IOTA 1810 organic silicon defoamer is developed in the introduction of foreign advanced technology, combined with bubble defoaming system, polyorganosiloxane as the main material,and it can quickly eliminate water bubbleas well as long bubble suppression effect. Dosage, less invasive, good permeability and good heat resistance, chemical stability, strong resistance to oxidation. No physiological activity, non-corrosive, non-toxic, no adverse side effects, combustion, explosion and high safety. In acid, alkali, salt, electrolyte, and can be used in hard water.it does not affect the basic properties of foaming system., and can be widely used in concrete admixture; Wastewater treatment; Printing and dyeing; The papermaking; Water-based coating; Chemical industry; Medicine, pesticide fermentation; Leather processing; Resin, emulsion polymerization; As well as a variety of metal cleaning fluid, cutting grinding fluid, coolant, detergent, adhesives and defoaming in aqueous system.
