Applications

NV-DF9306 can be used in a variety of industrial applications, including:

PCB printing inks

Oil-based and solvent-based inks

Epoxy flooring and resin systems

Antifreeze and automotive fluids

Vehicle and industrial oils

Cleaners and disinfectants

Solvent-based industrial formulations

Other non-aqueous systems requiring efficient foam control

Application Guide

NV-DF9306 is highly effective at low concentrations. A typical starting dosage is approximately 10–1,000 ppm, depending on the formulation, foaming tendency and processing conditions.

For difficult or highly foaming systems, higher concentrations may be required. The optimum dosage should be determined by laboratory and application testing.

For best performance:

• Agitate or homogenize the product before use.
• Where necessary, predilute NV-DF9306 with a suitable low-viscosity solvent to improve dispersion.
• Add the antifoam before or at the point where foam formation occurs, whenever practical.
• When used in solvent-based systems, ensure that the selected diluent is compatible with the formulation.
• The optimum dosage and addition method should be determined according to the specific application.

Solubility and Dispersion

NV-DF9306 has limited solubility in water and low-molecular-weight alcohols. It is readily dispersible or soluble in a variety of hydrocarbon-based solvents and mineral oils.

Suitable diluents should be selected according to the requirements of the specific formulation.

For systems with high sensitivity to surface defects, cratering or recoatability, compatibility testing is recommended before commercial use.

Recommended Use Level

General industrial formulations:10–1,000 ppm

Highly foaming systems:Higher dosage may be required

Difficult or special applications:Determined by application testing

The actual dosage depends on the composition of the foaming medium, processing conditions, agitation intensity, temperature and desired foam-control performance.

Handling & Precautions

Avoid prolonged exposure to excessive heat and direct sunlight. Before use, thoroughly agitate the product to ensure uniformity.

If the product is prediluted, use the diluted mixture as soon as practical and ensure that the selected diluent is compatible with the antifoam and the final formulation.

For detailed safety, handling and regulatory information, please refer to the applicable Safety Data Sheet (SDS).
