Application Area of BYK 182 CAS No. 108-65-6


Coating industry


Product characteristics and advantages

DISPERBYK-182 unflocculation of pigment by steric stabilization. Because the particle size of the flocculation pigment is small, it can obtain high luster, enhance color strength, and improve transparency or covering force. Due to the decrease of the viscosity, the fluidity can be improved, and the pigment content can be increased.


Recommended use


DISPERBYK-182 is widely used and suitable for solvent forms and water-based systems. It can be used alone or in conjunction with DISPERBYK-108 for the production of more economical solvent-based pigment concentrates.


Suggested dosage

Auxiliary dosage (purchased form) based on pigment:

Inorganic pigment: 15-20% titanium dioxide: 4-5%

Organic pigments: 30-60% carbon black: 80-100%


The above recommended amount is for reference, and the optimal amount should be determined through a series of tests.


Add method and processing guidance

To achieve optimal performance, the additives must be added to the abrasive, and then to the pigment. The resin and solvent components in the arbrasive were premixed, and then disperbyk-182 was slowly added in the stirred state. Pigments can only be added only after the additives are completely dispersed evenly.
