NUOSPERSE FA 196 is a highly concentrated liquid pigment dispersing agent for application in organic solvent-borne systems.
NUOSPERSE FA 196 is especially recommended for application as a dispersing agent for carbon black, for thermoplastic acrylic systems and as an auxiliary product to improve the action of universal tinting pastes in basic alkyd paints.

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
