DELTA-DC® 4054 is an electro-neutral wetting and dispersing additive to improve the wetting of pigment surfaces and organically treated Bentonites and to reduce the time required for the grinding process. DELTA-DC® 4054 is suitable for architectural paints.
It creates thixotropy and therefore prevents flooding, floating and settling of the pigments and reduces sagging.

Applications and usage:
DELTA-DC® 4054 is a wetting and dispersing agent for enhancing the dispersion of pigments and reducing the interfacial tension between pigments/extenders and the vehicle. By adding DELTA-DC® 4054 to the mill-base before the grinding process, a quicker wetting of the pigment/extenders as well as a better degree of dispersion will be obtained leading to the following advantages:
● Shorter dispersion time
● Improved storage stability
● Reduced flooding/floating and sedimentation
● Reduced tendency to sag (application on vertical surfaces)
DELTA-DC® 4054 is especially suitable for non-polar to medium-polar solvent-based and solvent-free coating systems such as:
● Air-drying alkyds
● Chlorinated polymers
● Alkyd/amino resin combinations
DELTA-DC® 4054 is ideal for dispersing organophilic Bentonites, because it reduces dispersion time, improves the storage properties of the final paste and gives a thixotropic, easily processed paste- product.
Used in anti-corrosion primers, in many cases the protective properties are enhanced. DELTA-DC® 4054 is not suited for Nitrocellulose varnishes (risk of discoloration).
0.5-2.0% (delivery form) on inorganic pigments
30.0-50.0% (delivery form) on the Bentonites
Safety and Handling:
DELTA-DC® 4054 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
DELTA-DC® 4054 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. DELTA-DC® 4054 has tendency to become hazy at low temperatures but this process can be reversed by heating.
50 kg and 180 kg non-returnable metallic containers.
