APPLICATION AND PROPERTIES
NUOSPERSE FA 196 is applicable in practically all organic solvent-borne paint and ink systems e.g., oxidatively drying systems, and thermoplastic systems.
As a dispersing agent for carbon black: An addition of ca. 1 % of NUOSPERSE® FA 196, calculated on the total quantity of the milling paste improves the colouring power and counteracts flocculation of various types of carbon black. NUOSPERSE® FA 196 must be added before the dispersing process.
As a pigment dispersing agent in thermoplastic acrylic systems and in non-aqueous dispersions: In both of the above mentioned systems, NUOSPERSE® FA 196 gives the following advantages:
• Higher gloss
• Better colouring power
• Better and quicker dispersion
