Product name:Fluorosilicone Antifoam Agent

Product code: NV-DF 9051

Active Ingredient: 100% Poly(3,3,3-trifluoropropylmethylsiloxane)

CAS No.: 63148-56-1

Product Description

NV-DF 9051 is a 100% active, non-reactive fluorosilicone fluid designed specifically for heavy-duty defoaming and antifoaming applications in aggressive environments. Due to its unique chemical structure, NV-DF 9051 provides extraordinary resistance to harsh chemicals, organic solvents, and extreme temperatures where conventional dimethyl silicone antifoams fail, dissolve, or promote foam. It delivers ultra-high efficiency and persistent foam suppression at extremely low addition rates.

Key Benefits & Features

Extreme Chemical & Solvent Resistance: Insoluble in chlorinated solvents, petroleum fractions, and most aliphatic hydrocarbons.

Efficient Foam Control:Provides rapid foam knockdown and long-lasting foam suppression at ultra-low dosages .

Wide Thermal Window: Maintains reliable performance across an extreme temperature range (-40℃to 204℃).

Low Surface Tension: The low surface tension of the fluorosilicone fluid promotes rapid spreading at the foam interface and contributes to efficient foam suppression.

Low Refractive Index: Provides good optical and formulation characteristics.

Non-Reactive Structure: Chemically inert, non-reactive and non-corrosive under recommended application conditions, with good resistance to oxidation.

Excellent Chemical and Solvent Resistance:Provides high resistance to aggressive chemical environments and selected organic solvents where conventional silicone antifoams may have limited compatibility.

Applications

Chemical & Petroleum Processing: Effective Defoamer for solvent-based chemical reactions, petroleum refining, and gas-liquid separation processes where conventional silicones are incompatible or chemically degraded.

Oil & Gas Industry: Foam control in severe solvent loops, amine units, glycol dehydration systems,and crude oil extraction systems.

Dry Cleaning & Chlorinated Solvents: Unique, specialized defoamer for chlorinated hydrocarbon systems and perchloroethylene systems where conventional silicones swell or dissolve.

Solvent-Based Formulations: Suitable for systems in which conventional polydimethylsiloxane antifoams may have insufficient compatibility or persistence.

Textile Industry: High-performance defoamer for solvent-based textile processing; also used in hydrophobic and oleophobic fabric finishing.

Fuel & Lubricant Systems：Specialized antifoam for aviation fuels, hydraulic fluids, and synthetic lubricants, where insolubility and chemical inertness are critical.

Harsh Chemical Environments: Suitable for strongly acidic, alkaline, or oxidizing media where standard

Application Guide

Recommended Dosage:

Starting evaluation level: 5 to 50 ppm based on total system volume.

Optimal dosage should be determined through bench trials, as requirements vary significantly with system viscosity, foam severity, and operating conditions.

Viscosity Selection:

Lower viscosity grades disperse more readily and act faster; higher viscosity grades provide longer-lasting foam control but require more vigorous agitation for adequate dispersion.

Handling & Precautions

Wear appropriate personal protective equipment (safety goggles, protective gloves).

Avoid direct contact with skin and eyes. In case of contact, flush immediately with plenty of water.

Avoid inhalation of solvent vapors during the dilution step.

Storage & Packaging:

Packaging Options: Available in 5 KG, 25 KG, and 250 KG plastic drums.

Storage Conditions: Store in tightly sealed, airproof containers in a cool, dry, and well-ventilated location. Keep away from direct sunlight, heat, open flames, strong acids, alkalis, and oxidizing agents.

Transport: Classified and transported as non-dangerous goods.

Shelf Life: 24 months from the date of manufacture when stored in unopened, original containers under recommended conditions.
