Antifoaming agents are the right choice as they are superior in many ways to the conventional types. NKAF series:
• Provide high efficiency.
• Cover a broad spectrum of applications.
• Are largely chemically inert; i.e., they do not interfere with the chemical process.
• Are added in small quantities only and do not reduce or hinder product efficacy.
These Antifoaming agents spread over the foam, the active ingredient displaces the surfactant and thins out the lamellae, leading to destabilization and eventual foam collapse.
Process of Production of Phosphoric Acid
SALIENT FEATURES
• Better dispersing properties.
• Long term action in the reactive media.
• Better compatibility.
• High temperature stability.
• They are stable to cold and heat and can be stored without a problem. Storage at room temperature is recommended.
Product Data Sheets are enclosed and from them it may be noted that they are composed of a synergistic blend of organic ingredients comprising of sulphosuccinates and other surfactants suitably formulated on aqueous vehicle and the formulations are acid compatible and easy to dilute if necessary and dose for foam control. The products do not flash at the temperature conditions at which they are used and are non-flammable.
