Applications & Uses+
DELTA-DC 4242 is a wetting and dispersing agent for inorganic and organic
pigments; and fillers/extenders in solvent-based, solvent-free and water-based
systems. The advantages are:
Reduced grinding and dispersion time
Improved gloss and flow
Increased pigment loading in the mill-base or pigment concentrate
enabling to achieve VOC levels below 250 g/l in highly filled solventbased
DELTA-DC® 4242 can be used in all solvent-based and solvent-free industrial and
decorative coating systems. It is especially suitable for wetting, dispersion and
stabilization of inorganic pigments and fillers in solvent-free systems. DELTA-DC®
4242 can also be used to decrease the viscosity in the millbase or pigment
concentrate when combined with high molecular weight dispersants.
When used in water-based applications, it is recommended to neutralize DELTADC
® 4242 with an amine to pH 7.5 - 8.0 to make it water-soluble.
DELTA-DC® 4242 should be added prior to the dispersion process.
2.0-4.0% on inorganic pigments or fillers/extenders
5.0-7.0% on organic pigments
DELTA-DC 4242 improves the pigment wetting and reduces the dispersion time
of inorganic pigments (particularly Ti02) and a few organic pigments.
Deflocculation of pigments when using DELTA-DC® 4242 can lead to improved
gloss, rheology and levelling of the final ink.
It has broad solvent compatibility and is suitable for use in both alcohol- and
acetate-reduced nitrocellulose printing inks and pigmented bases. DELTA-DC®
4242 is well-suited to packaging flexographic applications.For best results, DELTA-DC® 4242 should be combined with the pre-blended
liquid portion of the mill-base formulation before addition of the pigment.
2.0-5.0% on inorganic pigments
5.0-8.0% on organic pigments
DELTA-DC® 4242 facilitates the incorporation of fillers and pigments in PVCPlastisols
and solventfree epoxy floorings. Through this improvement of the
dispersing process, a more homogeneous distribution of fillers/extenders and
pigments is achieved. In addition, a strong viscosity reduction is obtained. The
dispersing of organic pigments in plasticizers or other liquid phases can result in
increased color strength.
DELTA-DC® 4242 is especially suitable for wetting, dispersion and stabilization
of inorganic pigments and fillers in solvent-free epoxy and polyurethane systems,
like flooring or pipe-line coatings.
DELTA-DC® 4242 should be mixed with the plasticizer prior to the addition of the
fillers/extenders and pigments.
