DELTA-DC® 4212 

DELTA-DC® 4212 is a wetting and dispersing additive for solvent-based and solvent-free coatings to improve pigment wetting, reduce the grinding time and stabilize the pigment dispersion. 

DELTA-DC® 4212 is suitable for stabilizing inorganic pigments and extenders and strongly reduces mill-base viscosity. 

DELTA-DC® 4212 is suitable for coatings and composite. 


Composition :Acidic polyether 

Density :ca. 1.25 g/cm3 

Appearance :Clear brownish liquid 

Acid value :270-310 mg KOH/g 

Active ingredients :100% 

Applications and usage: 


DELTA-DC® 4212 is a conventional dispersant for solvent-based coatings to improve pigment wetting, reduce the dispersion time and increase gloss and flow. It is particularly suitable for stabilizing titanium dioxide and extenders. DELTA-DC® 4212 strongly reduces mill-base viscosity allowing high pigment loading. 

It is suitable for the following applications: 

    ●    General industrial coatings 

    ●    Transportation coatings (OEM and car refinish) 

    ●    Acid-catalyzed systems (e.g. coil coatings) 

    ●    PU sanding sealers (e.g. wood coatings) 

DELTA-DC® 4212 should be added prior to the dispersion/grinding process. 

5.0-10.0% (delivery form) on inorganic pigments 

1.0-4.0% (delivery form) on TiO2 and extenders 


DELTA-DC® 4212 is an efficient wetting and dispersing agent for inorganic fillers, especially CaCO3 and ATH in unsaturated polyester resin systems. This results in: 

    ●    Improved wetting and incorporation of extenders 

    ●    Reduced viscosity of the paste/compound 

    ●    Increased filler and extender load 

DELTA-DC® 4212 is suited for filled unsaturated polyester systems (sheet and bulk moulding compounds, gelcoats and putties) or combination of polystyrene, polyvinylacetate and styrene- butadiene copolymers (e.g. LS- or LP-formulations). 

DELTA-DC® 4212 is directly added to the unsaturated polyester resin while stirring prior to the addition of the extenders. 

0.5-1.0% (delivery form) on extenders 

Safety and Handling: 

DELTA-DC® 4212 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


DELTA-DC® 4212 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. 


50 kg and 180 kg non-returnable metallic containers.
