Product name:Silicone Defoamer for Saponified Oils & Emulsion Cutting Fluids

Product code: NV-DF 9104

Chemical Characterization:Polyether-Modified Silicone Compound

Product Description

NV-DF9104 is a 100% active polyether-modified silicone defoamer engineered specifically for metalworking fluid (MWF) matrices. Formulated with a specialized silicone compound and a customized emulsification system, it achieves an optimal balance between fast foam knockdown and long-lasting suppression.

Its unique structure delivers exceptional system compatibility, outstanding dilution stability, and superior resistance to high-shear environments. NV-DF9104 provides highly effective foam control at extremely low treat rates, minimizing any potential side effects on final fluid formulations. It is exceptionally well-suited for saponified oil systems, fully synthetic, semi-synthetic, and emulsion cutting fluids.

Typical propertes:

Appearance”White to light milky viscous liquid, no sediment

Viscosity (25℃):800–2000 mPa.s

Active Matter (%):100% (Concentrate)

Ionic:Non-ionic

Solubility:Dispersible in water

Key Benefits & Features

Tailored for Metalworking Fluids: Specifically optimized for direct tank-side or concentrate addition in cutting fluid formulations.

Ultra-Low Dosage Efficiency: Delivers superior performance at ultra-low treating levels.

Long-Lasting Suppression: Maintains sustained defoaming efficiency under continuous high-shear fluid circulation.

Superior Stability: Demonstrates excellent storage stability and outstanding high-shear resistance without phase separation.

Applications

NV-DF9104 is broadly recommended for foam control in water-dilutable metalworking fluids and circulating systems, including:

Semi-synthetic and emulsion-type cutting fluids

Fully synthetic metalworking formulations

Saponified oil solutions and coolant systems

High-shear industrial fluid circulation systems requiring high dilution stability

Application Guide

Recommended Dosage: Typically 1 to 20 ppm based on system conditions (temperature, agitation rate, and fluid dynamics). Optimal loading should be verified through laboratory testing.

Incorporation Method: Can be added directly into the foaming system or pre-diluted with water before addition. Ensure thorough dispersion upon addition. Pre-diluted mixtures should be used within 4 hours to maintain optimal performance.

Synergistic Performance: Depending on specific application environments, NV-DF9104 can be paired with NV-DF9103 for maximum synergistic foam suppression.

Handling & Precautions

Wear appropriate protective eyewear and gloves during handling.

Ensure adequate local ventilation in operating areas.

Clean up spills immediately using absorbent sand or sawdust to prevent slip hazards.

Keep container tightly closed when not in use. Avoid mixing directly with concentrated strong acids or oxidizers.
