QM-2380 Dispersant

Product Overview:

QM-2380 is a polymeric superdispersant containing pigment-affinic groups, suitable for grinding various organic pigments, carbon black, and iron oxide pigments in low-polarity systems. It not only exhibits excellent wetting properties but also provides superior anti-settling, anti-flocculation, and anti-floating/streaking capabilities. QM-2380 is also suitable for the dispersion of organoclay and can be used in the dispersion process during masterbatch manufacturing (superior to PE wax-based dispersants).

Physicochemical Parameters:

Ingredients: High molecular weight polymer containing pigment-attracting groups

Appearance: Reddish-brown viscous liquid or wax-like substance

Active content: 100%

Decomposition temperature: >295°C

Flash point: 260°C

Product Characteristics:

Suitable for low-polarity systems (low-polarity aliphatic solvent-based systems), such as petroleum resins, hydrocarbon resins, alkyd resins, and chlorinated rubber systems, for the dispersion of pigments and organoclays;

It is a polymeric superdispersant with excellent wetting properties. Compared to small-molecule wetting and dispersing agents, it has superior ability to prevent pigment re-agglomeration.

Application Systems:

Suitable for the dispersion of organic pigments and bentonite in low-polarity systems:

Ideal for the manufacture of PE/PP/PVC-based low-polarity resin masterbatches, especially suitable for the dispersion of organic pigments, iron oxide pigments, and carbon black:

Suitable for the dispersion of organic pigments, carbon black, and iron oxide in plasticizer pastes and aliphatic solvents.

Recommended Dosage: 

Inorganic pigments: 1.5~5%

Organic pigments: 10~30%

Ordinary carbon black: 15~30%

High-pigment carbon black: 40~75%

Packaging and Storage:

25 kg/drum.

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

Crystallization may occur at temperatures below 10°C; however, this does not affect its effectiveness after being heated back to a liquid state.
