DELTA-DC® 4066 

DELTA-DC® 4066 is a wetting and dispersing additive for enhancing the dispersion of inorganic pigments. It is designed to prevent flooding and floating and hard sedimentation. 


Composition :High molecular weight unsaturated carboxylic acid 

Solvent(s) :Alkylbenzene/diisobutylketone 

Specific gravity @ 20°C :ca. 0.95 g/cm3 

Flashpoint :40 °C 

Appearance :Transparent, slightly brownish liquid 

Acid value :120-160 mg KOH/g 

Active ingredients :52% 

Applications and usage: 


DELTA-DC® 4066 has a chemical structure that is similar to that of DELTA-DC® 4065, but does not contain the organically modified polysiloxane. 

Like DELTA-DC® 4065, DELTA-DC® 4066 can be used to improve the pigment wetting and stabilize the pigment dispersion. 

It produces a controlled flocculation of pigments and extenders and therefore prevents flooding/floating and hard sedimentation. DELTA-DC® 4066 is also used in amine-neutralized aqueous coatings, but it is not compatible with mineral spirits or paints, which are diluted with mineral spirits. 

DELTA-DC® 4066 is suitable for medium- to high-polar systems such as: 

    ●    Nitrocellulose systems 

    ●    Alkyd/amino resin combinations 

    ●    Polyurethane and chlorinated polymer systems 

    ●    Acrylic polyisocyanate systems (two-pack acrylics) 

DELTA-DC® 4066 is particularly effective in preventing flooding of titanium dioxide in combination with other color pigments. 

It is often used in conjunction with high molecular weight dispersants such as DELTA-DC® 3011DELTA-DC® 3046, DELTA-DC® 3047 or DELTA-DC® 3401. However, the performance of DELTA-DC® 4065 in most cases will be slightly better. 

When used in anti-corrosion primers, in many cases the protective properties are enhanced. DELTA-DC® 4066 should be added prior to the dispersion process. 

0.5-2.5% (delivery form) on inorganic pigments 

Safety and Handling: 

DELTA-DC® 4066 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


DELTA-DC® 4066 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The production date is indicated on the container. 


55 kg and 200 kg non-returnable metallic containers.
