DELTA-DC® 4040 

DELTA-DC® 4040 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® 4040 is suitable for stabilizing inorganic pigments and extenders and strongly reduces mill-base viscosity. 

DELTA-DC® 4040 is suitable for coatings and composite. 


Composition :Solution of an acidic polyester polyamide 

Solvent(s) :Xylene/n-butylacetate 

Appearance :Transparent, yellowish liquid 

Acid value :60-80 mg KOH/g 

Active ingredients :56% 

Applications and usage: 


DELTA-DC® 4040 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® 4040 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® 4040 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® 4040 is an efficient wetting and dispersing agent for inorganic fillers. This results in: 

●    Improved wetting and incorporation of extenders 

●    Reduced viscosity of the paste/compound 

●    Increased extender load 

DELTA-DC® 4040 is suited for filled unsaturated polyester systems (sheet and bulk moulding compounds, gelcoats and putties). 

DELTA-DC® 4040 should be added to the resin system while stirring prior to the addition of the extenders. 

0.5-2.0% (delivery form) on extenders 

Safety and Handling: 

DELTA-DC® 4040 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet. 


DELTA-DC® 4040 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.
