GENERAL DESCRIPTION:
ANJEKA-6503 is a copolymer containing acidic functional groups. It serves as a dispersant suitable for solvent-based/UV coating systems and inks, specifically designed for dispersing matting agents and inorganic pigments.
PRODUCT DATA:
Chemical Composition: Copolymer with acidic functional groups
The data provided on this datasheet represents typical values and is not indicative of product specifications.
| Appearance: | Yellow to brown liquid |
| Acid Value (mgKOH/g): | 50-150 |
| Density (g/cm³ at 23℃): | 1.05-1.15 |
| Viscosity (cps at 25℃): | 300-800 |
| Non-volatile Content (%): | 98 |
STORAGE and TRANSPORTATION:
Thoroughly stir before use, as layering or oiliness may occur at temperatures below 0℃. Heat to 30℃—40℃ and mix uniformly. Storage time is not recommended to exceed 12 months.
SPECIAL NOTES:
Due to the relatively high acid value of the product, it may catalyze cross-linking in baking paint systems, leading to an increase in viscosity during the storage of coating systems. In PE systems, it might reduce coating drying speed. The optimal dosage should be determined based on actual experimental conditions.
APPLICATION GUIDELINES:
Coatings Industry and Printing Inks
Key Features and Benefits:
This additive employs spatial hindrance to disperse pigments effectively, ensuring stability throughout the coating process. The reduction in particle size of dispersed pigments within matting agent systems results in a refined and even surface appearance, eliminating any blooming effects. This leads to an enhancement in gloss, color intensity, and transparency within the coating. Furthermore, the additive brings about a substantial decrease in viscosity, thereby improving flow properties and enabling an increased loading of matting agents. In applications involving high-speed electrostatic spray of inorganic pigments, it significantly minimizes overspray.
Application Areas:
Highly recommended for utilization in both solvent-based and solvent-free coatings, as well as printing inks, with a primary focus on stabilizing inorganic pigments, particularly titanium dioxide. Its anionic nature positions the additive as an optimal choice for systems catalyzed by acids, such as coil coatings.
RECOMMENDED LEVELS:
Additive levels (as purchased) based on pigment quantity:
| Matting Agents: | 10%-50% |
| Inorganic Pigments: | 1%-6% |
The above data is based on empirical quantities; optimal levels should be determined through a series of experiments.
PROCESSING INSTRUCTIONS:
For optimal performance, the additive should be added to grinding materials first before introducing pigments.
