QM-6368B Silicone Antifoaming Agent

Product Overview:

QM-6368B is a fumed silica-modified silicone defoamer, suitable for solvent-based and solvent-free coatings and ink systems. It possesses strong defoaming and foam-inhibiting capabilities, along with high efficiency, providing excellent defoaming effects even at very low addition levels. It is particularly suitable for eliminating microbubbles in high-viscosity coating and ink systems. Compared to QM-6368A, QM-6368B has slightly better compatibility but slightly weaker defoaming performance, and is especially suitable for various ink systems.

Physicochemical Parameters:

Ingredients: Fumed silica modified polysiloxane

Appearance: Milky white, turbid, viscous liquid

Active content: 100%

Product Characteristics:

Suitable for solvent-based coating systems, it possesses excellent defoaming capabilities and can quickly break down foam;

Particularly suitable for pigment-containing systems; for high-gloss clear coats and colored paints, its compatibility needs to be carefully evaluated;

It exhibits extremely high defoaming efficiency, showing excellent results even at very low addition levels.

Application Systems:

It is suitable for various screen printing, UV curing, and PCB inks, as well as other solvent-based coating systems such as two-component epoxy and polyurethane.

Recommended Dosage: 

Generally, the addition amount is 0.05% to 0.5% of the total weight, but in some ink systems, the addition amount can be as high as 3% to 5%. It is recommended to add it before grinding, but it can also be added at any stage of production. After adding, high-speed stirring is required to achieve good dispersion.

Packaging and Storage:

25 kg/drum.

The product should be stored in a cool, well-ventilated place. When unopened, the shelf life is 24 months from the date of manufacture.
