| Résumé : |
Cu-phthalocyanine pigments represent one of the major classes of organic pigments that are used in the coatings and ink industries. Although used extensively, dispersing these pigments is by no means without a challenge. Especially as the rheological behaviour of the mill base can be difficult to control, which might lead to decreased pigment loading or the need for a synergist. Such synergists usually have a positive effect on rheology but can lead to leaching problems in the final application.
In order to fulfil the market needs, two dedicated dispersing agents have been added to BASF's portfolio.
Its most recent products, Efka PX 4350 and Efka PX 4351 are high performance dispersing agents, specially developed for processing Cu-phthalocyanine pigments ; their use ensures peak performance in viscosity reduction and optimum colour development in high-end solvent-based applications including high solids. |
