Product name:High-Concentration Silicone Defoamer Emulsion for Metalworking Fluids

Product code: NV-DF 9106

Chemical Characterization:Organo-Silicone Emulsion

Product Description

NV-DF9106 is a 65% high-concentration silicone defoamer emulsion designed for foam control in water-based metalworking fluids and circulating coolant systems.

It is particularly suitable for incorporation into semi-synthetic and emulsion-type cutting fluid formulations, where effective and durable foam control is required.

NV-DF9106 provides good system compatibility, low dosage requirements and good shear stability, making it suitable for metalworking fluid systems subject to circulation and agitation.

Typical propertes:

Appearance:Milky white liquid

Chemical Type:Organo-silicone emulsion

Active Content (wt%):(65 ± 1)%

pH Value (Direct):6.0 – 8.0

Ionic:Non-ionic

Solubility:Dispersible in water

Key Benefits & Features

High Active Content: Contains 65±1% active silicone, providing a concentrated solution for foam-control applications.

Low Dosage: Effective foam control can be achieved at low addition levels depending on formulation and operating conditions.

Good Compatibility: Designed for incorporation into suitable cutting fluid and coolant formulations.

Shear Stability: Provides good foam-control performance in circulating and agitated fluid systems.

Long-Lasting Foam Control: Provides persistent foam-control performance under suitable application conditions.

Suitable for Metalworking Fluids: Particularly suitable for semi-synthetic and emulsion-type cutting fluid systems.

Applications

NV-DF9106 is specifically recommended for demanding metalworking and circulating fluid systems:

Semi-synthetic metalworking cutting fluids

Emulsion-type coolants and soluble oil fluids

High-shear industrial fluid circulating loops

Industrial processing applications requiring high dilution stability and shear endurance

Application Guide

Recommended Dosage: Typically 1 to 20 ppm based on operating conditions (temperature, circulation velocity, and aeration dynamics). Optimal loading should be determined via laboratory ladder testing.

Incorporation Method: Can be added directly into the foaming system or pre-diluted with water prior to incorporation. Ensure uniform dispersion upon addition. Pre-diluted emulsion mixtures should be consumed within 4 hours to preserve peak performance.

Synergistic Performance: Depending on the specific application conditions, NV-DF9106 may be used in combination with NV-DF9108.The optimum combination ratio and dosage should be established through application testing.

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.
