Solvent based dispersant HH2015

• HH-2015 Solvent-based dispersant

It is a high molecular weight dispersant suitable for solvent-based industrial coatings and automotive coatings, which is polymerized by controlled free radical technology (CFRP). This dispersant has good pigment dispersion performance and is widely compatible with various resin systems. It is suitable for resin-free color paste (RFPC).

• Recommended Use

It has a wide compatibility and is suitable for various solvent-based industrial and automotive paints. It can be applied to resin-free color pastes designed for different resin systems.

Addition amount

Recommended Levels

Recommended dosage: The following dosage is based on the ratio of dispersant solids to pigments:

Inorganic pigments: 20-30% by oil absorption

Organic pigments: green, blue, purple: 15-30% by BET value; yellow, red, orange: 25-45% by BET value

Carbon black low pigment: 15-20% by DBP absorption value

Carbon black high pigment: 50-80% by DBP absorption value

*. The above data are empirical dosages(calculated according to the supply form), and the optimal dosage needs to be determined through a series of tests.

Incorporation and Processing Instructions

To achieve the best performance, the additives should be added to the grind first, followed by the pigment. Premix the resin and solvent components of the grind, then slowly add the additives while stirring. Do not add the pigment until the additives are well mixed.
