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
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.
