Amine value :36-42 mg KOH/g
Acid value :4-8 mg KOH/g
Appearance :Turbid and yellowish liquid
Active ingredients :41.5%
Applications and usage:
DELTA-DC® 3590 is a cost-effective high molecular weight dispersion control additive for enhancing the dispersion of organic/inorganic pigments and carbon blacks in aqueous media.
DELTA-DC® 3590 is compatible with a wide range of resin and vehicle systems and considered suitable for VOC-free applications. It can be used in resin-containing as well as in resin-free applications to produce pigment concentrates for water-based coatings.
DELTA-DC® 3590 stabilizes the pigment dispersion of all kinds of pigments and provides the following properties:
● Reduced viscosity of the mill-base leading to higher pigment loading
● Excellent gloss
● Flocculation stability
● Anti-flooding behavior Broader compatibility
DELTA-DC® 3590 is pH-independent, completely water-soluble and does not require neutralization.
DELTA-DC® 3590 should be incorporated in the mill-base before adding the pigments.
Inorganic pigments :10% of oil absorption value (solid form)
Organic pigments :30-50% of BET value (solid form)
Carbon blacks :25-30% of DBP value (solid form)
When used in resin-free pigment concentrates, the following addition levels are advised:
Inorganic pigments :15-25% of oil absorption value (solid form)
Organic pigments :30-60% of BET value (solid form)
Carbon blacks :50-60% of DBP value (solid form)
DELTA-DC® 3590 is a polymeric dispersant for enhancing the dispersion of organic pigments in aqueous media. This results in:
Lower viscosity of concentrates and/or increased pigment loading
Improved color strength, transparency and gloss of inks
DELTA-DC® 3590 is pH-independent, completely water-soluble and does not need to be neutralized. It has no detrimental impact on the resistance properties of the dried film.
DELTA-DC® 3590 has been developed for water-based pigment bases and printing ink formulations for flexographic application. It is considered suitable for VOC-free applications and can be used with a wide range of industry pigments and carbon blacks.
DELTA-DC® 3590 is compatible with a wide range of resin/vehicle systems.
DELTA-DC® 3590 should be incorporated in the mill-base.
Organic pigments :25-50% of BET value (solid form)
Carbon blacks :20-30% of DBP value (solid form)
In resin-free pigment concentrates, the optimal use level may be higher.
Safety and Handling:
DELTA-DC® 3590 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
DELTA-DC® 3590 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.
