BYK-3955 P – The additive is recommended for the use in powder coatings to improve the acceptance of pigments, especially carbon blacks. Proper incorporation of the additive in the extruder is required to have a positive influence on gloss and leveling of the powder coating and to prevent formation of craters, fish eyes and seeds.
DISPERBYK-198 – DISPERBYK-198 is designed for the production of water-borne pigment concentrates. This high molecular weight additive deflocculates pigments through steric stabilization. DISPERBYK-198 is highly effective on many organic pigments and carbon blacks. Color strength, transparency, gloss and storage stability of the pigment concentrates are improved. The additive can also be used in slurries to which surfactants or solvents have been added.
