Application Guide

Grinding Stage

NV-DF9045 is particularly suitable for addition during the grinding or pigment dispersion stage of waterborne formulations.

Addition during the grinding stage is recommended where high shear is available to facilitate effective incorporation and foam control.

Let-Down / Varnish Stage

When NV-DF9045 is added during the paint mixing, let-down or varnish stage, high shear dispersion or pre-dilution is recommended to facilitate uniform incorporation into the formulation.

The appropriate pre-dilution method should be selected according to the specific formulation and processing conditions.

Dosage

The optimum dosage and addition point should be determined through application testing according to the specific formulation, processing conditions and foam generation characteristics.

Handling & Precautions

Slight separation or settling may occur after long periods of standing. This is normal and does not impact quality; always mix thoroughly before use to ensure perfect product uniformity.

Keep containers tightly closed when not in use to prevent atmospheric moisture contamination.

Storage：

Temperature Range: Store in original, un-opened packaging at temperatures between 5℃and 40℃. Protect from freezing and direct extreme heat.

Shelf Life: The minimum shelf life is 12 months from the production date, provided it is kept in air-tight containers under recommended parameters.
