Dispersant HY-4310

Overview:

Polymeric dispersants for solvent-borne industrial coatings and automotive coatings using controlled radical technology (CFRP) polymerization. It has highly effective pigment dispersion properties and broad compatibility with a wide range of resin systems. This feature is ideal for resin-free colorants (RFPC).

Technical specifications:

Active component: 50%

Solvent: propylene glycol methyl ether acetate

Amine value: 20mg KOH/g DIN 16945

Colour: Big 9 ASO 4630

Appearance: Clear, light orange liquid

Product Features:

1. Improve the color development of organic pigments

2. Suitable for dispersion of ultra-fine carbon black.

3. Effectively reduce the viscosity of high-concentration colorants during grinding.

Suggested dosage and usage method:

It has a very wide range of compatibility and is particularly suitable for a wide range of solvent-based industrial and automotive paints. Recommended for resin-free colorants designed for different resin systems.

Recommended dosage: The following dosage is based on the ratio of the solid content of the dispersant to the amount of pigment:

Inorganic pigments: 20-30% according to oil absorption

Organic pigments: green, blue, violet: 15-30% according to BET value; Yellow, Red, Orange: 25-45% by BET value

Low pigment carbon black: 15-20% according to DBP absorption value

High pigment carbon black: 50-80% according to DBP absorption value

0.1%~0.5% of the amount of resin when added or 1%~5% of the amount of resin when modified.

Packaging and storage requirements:

25kg iron drum, 200kg iron drum. Sealed storage, storage period at room temperature for 24 months.
