Good Substrate Wettability Wetting Leveling Agent For Water Based Inks
Wetting and leveling Agent DR-4900 is an unstable foam-type wetting and leveling additive with a special structure, provides excellent substrate wettability, defoaming properties, and prevents leveling shrinkage holes.
Specification:
| Item | Value |
| Appearance |
Light yellow transparent liquid |

Active ingredient content |
>99% |
Characteristics:
When used in water-based coatings or water-based inks, it can promote pigment wetting and dispersion, prevent pigment flocculation, thereby improving the storage stability of formulations, and enhance gloss and coloring ability.
When used in non-aqueous systems, it can effectively improve system flowability, enhance coating leveling, and to some extent balance the static and dynamic surface tension of the system, improving the coating performance.
Recommended dosage and usage method:
It can be added in the form of the original product or a pre-diluted solution. Pre-diluting with the recommended solvent can simplify the addition and mixing process. Dosage: 0.2-2% based on the total formula.
Application:
It is widely used and safe and effective. However, the dosage and foaming stability should be determined through experiments before use. This additive is recommended for all water-based and solvent-based coatings, inks, and some radiation-curable systems.
Packaging and storage :
25kg /drum or 200kg/ drum; The shelf life of unopened products is 24 months.
Store in a sealed container in a cool, dry, and well-ventilated place, away from fire and heat sources. It should be kept moisture-proof, protected from direct sunlight, and prevent contamination from strong acids, strong alkalis, and rain.
