Product name:Silicone Defoamer for Water-Based Color Paste Grinding

Product code: NV-DF 9042

Active Ingredients: 100% Polysiloxane-Polyether Copolymer with a Special-Structure Active Synergist

Product Description

NV-DF9042 is a 100% active, solvent-free silicone defoamer based on a polysiloxane-polyether copolymer system. A special-structure active synergist is incorporated to enhance foam control performance while maintaining good compatibility with the formulation.

NV-DF9042 provides effective defoaming and antifoaming performance in a variety of water-based polymer systems. It is particularly suitable for use during the grinding process of water-based color pastes, where effective foam control is required during high-shear processing.

The product is suitable for styrene/acrylic systems, pure acrylic emulsions, polyvinyl alcohol (PVA) and water-based epoxy systems.

Application Guide

Recommended dosage

Dosage NV-DF9042 is approximately 0.1–0.5% based on total formulation weight.

The optimum dosage should be confirmed through application testing according to the specific formulation and processing conditions.

Grinding Process

NV-DF9042 is particularly suitable for use during the grinding process of water-based color pastes.

Due to its relatively high viscosity, pre-dilution is recommended before addition to facilitate incorporation and improve dispersion efficiency.

Coating and Ink Production

When NV-DF9042 is used during coating or ink production, high-shear dispersion is recommended to ensure effective incorporation into the formulation.

The optimum addition point and dosage should be determined according to the specific formulation and processing conditions.

Handling & Precautions

Product homogeneity is critical; always blend or stir the container thoroughly prior to each dispensing loop, as the high-viscosity matrix contains dispersed particles that may settle over long storage.

Avoid contact with eyes; flush thoroughly with fresh water upon accidental exposure.

Storage：

Temperature Range: Keep stored within sealed factory containers between 5℃and 35. Avoid freezing conditions.

Shelf Life: Stable for up to 12 months from the date of chemical packaging under proper tightly closed conditions.
