QM-5331 Non-silicone defoamer

Product Overview:

QM-5331 is a non-silicone defoamer suitable for solvent-based and solvent-free coatings. It exhibits strong foam suppression, defoaming, and foam breaking effects, and is particularly suitable for high-viscosity coating systems. It also has good compatibility and is less likely to cause cratering in the system, offering good safety in use.

Physicochemical Parameters:

Ingredients: Acrylate Copolymer

Appearance: Colorless to light yellow viscous liquid

Active content: 100%

Product Characteristics:

Modified acrylate copolymer can maintain strong defoaming properties while improving the flow properties of coatings and increasing film flatness;

It solves the problem of difficult defoaming in high-viscosity systems, inhibits the introduction of air bubbles during stirring, and helps release tiny bubbles from the coating;

It is suitable for thick-film systems, solving the problems of foaming and pinholes that easily occur during thick coating, resulting in a smooth film surface;

It is suitable for dipping, curtain coating, and other application environments, and helps in the removal of air bubbles when applied to porous substrates.

Application Systems:

Suitable for two-component PU, amino baking paints, nitrocellulose dip coatings, acid-curing amino resins, epoxy resins, and other solvent-based and solvent-free coating systems.

Recommended Dosage: 

For a total concentration of 0.1-1.0%, please test to determine the optimal dosage: the additive should be mixed under sufficiently high shear force, and it is recommended to add it before grinding.

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.
