QM-1728 Water-based Dispersant

Product Overview:

QM-1728 exhibits excellent pigment wetting and stabilizing effects, making it ideal for use in epoxy systems, especially water-based epoxy primers, such as container coating primers. It disperses inorganic fillers and organic pigments, improving wetting and dispersion, enhancing pigment stability and color development, and offering high cost-effectiveness. QM-1728 is particularly suitable for dispersing and stabilizing zinc powder in water-based zinc-rich primers, achieving excellent viscosity reduction, color development, and storage stability.

Physicochemical Parameters:

Composition: Special high molecular weight polymer

Appearance: Light yellow transparent liquid

Active component: 60%

Soluble: Propylene glycol methyl ether

Product Characteristics:

Suitable for water-based, water-soluble, and alcohol-soluble coating systems, especially epoxy systems, such as container epoxy zinc-rich primers and epoxy intermediate coats, as well as water-based epoxy anti-rust paints for corrosion protection;

It belongs to the high molecular weight dispersant category and has excellent wetting properties. Compared to small molecular weight wetting and dispersing agents, it has excellent anti-coarsening ability.

Application Systems:

Suitable for water-based or water-soluble systems, especially for the dispersion and stabilization of zinc powder in water-based epoxy systems.

Recommended Dosage:

Percentage of effective dispersant to pigment weight: Titanium dioxide: 2-5% Inorganic pigments: 3-10% Filler: 1-2% Zinc powder: 1-5% of zinc powder weight

Packaging and Storage:

25kg/drum or 200kg/drum.

The product should be stored in a cool, ventilated place. Unopened, the shelf life is 12 months from the date of production.
