Efka® FA 4611 is a solvent-free wetting and dispersing agent. It shows outstanding performance in dispersing and stabilizing of inorganic pigments - in particular titanium dioxide.
Description
Efka FA 4611 is a solvent-free wetting and dispersing agent with acidic groups, excellently suited for solvent-borne and solvent-free coatings and printing inks. It offers broad compatibility in a wide range of resin systems, is very efficient in wetting and dispersing titanium dioxide and other inorganic pigments, allows high pigment and filler loading, strongly reduces millbase viscosity, and is suitable for high gloss systems. Among BASF's Efka FA-series dispersing agents processed in this session, see alsoEfka FA 4608 and Efka FA 4609for related inorganic-pigment dispersants, and Efka FA 4644 for a low-molecular-weight dispersant also suited to organic pigments and bentonite gels.

Application
Efka® FA 4611 is a solvent-free wetting and dispersing agent. It shows outstanding performance in dispersing and stabilizing of inorganic pigments - in particular titanium dioxide.
Efka® FA 4611 is excellently suited for solvent-borne and solvent-free coatings and printing inks. It shows excellent pigment grinding properties in white UV flexo- and screen inks and coatings based on TiO2.In combination with a universal solvent-based grinding resin like Laropal® A 81, low mill base viscosities with reduced pseudo plastic flow behavior can be achieved.
Efka® FA 4611 is suitable for many coating systems such as:
● automotive OEM and refinish coatings
●
solvent-born and solvent-free industrial coatings
●
coil coatings
●
wood coatings
● radiation curable inks (UV inks)
● reactive resins and composites
