DELTA-DC® 4242 is an anionic wetting and dispersing agent for inorganic and organic pigments; and fillers/extenders. It is suited for solvent-based, solvent-free and water-based applications. Reduced viscosity can be obtained in the mill-base or pigment concentrate when combined with high molecular weight dispersants.
DELTA-DC 4242 can be used in coatings, printing inks and composite.

Applications and usage:
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 solvent-based systems
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 mill- base or pigment concentrate when combined with high molecular weight dispersants.
When used in water-based applications, it is recommended to neutralize DELTA-DC® 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 PVC-Plastisols and solvent- free 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.
