The high-quality stabilization of phthalocyanine pigments and carbon blacks in solvent-borne coating systems, printing inks and inkjet inks was the driver for developing DISPERBYK-2200.
To meet the challenges of very small particles – accompanied by a very large specific surface area – and various surface treatments of the phthalocyanine pigments, the development of a new type of polymeric structure had become necessary. This led, for the first time in the company's history, to the large-scale realization of a solid wetting and dispersing additive and utterly convinced the jury, who awards the internal innovation prize each year.
DISPERBYK-2200, which is available in pellet form, is characterized in particular by significant reduction of the grinding and final application viscosity, obvious improvement in the color strength and transparency of phthalocyanine pigments, and increased jetness of fine-sized carbon blacks in solvent-borne applications. In addition, the newly developed polymeric structure type, in combination with the large-scale manufacture of solid wetting and dispersing additives that has been achieved, forms the perfect basis for future product developments – precisely in those areas of application which it is virtually impossible to develop with products delivered in liquid form.
