2.2 Core Performance Features
1. Controlled low oil absorption slows viscosity growth, suitable for liquid ink and powder coating manufacturing.
2. Moderate surface oxidation ensures stable dispersion without excessive resin consumption.
3. Balanced jetness and gloss, delivers uniform black shade on porous and non-porous printing substrates.
4. Low heat generation during high-speed printing, reduces bubble and ink stacking defects.
5. Stable batch color consistency, suitable for leather color paste and textile printing tint.
2.3 Main Application Fields
1. Printing Inks: Offset litho ink, heat-set rotary ink, flexible packaging liquid ink
2. Coating Systems: General industrial finish, powder coating, water-based wall colorant
3. Color Dispersions: Leather black color paste, textile printing base tint, universal pre-dispersed colorant
4. Plastic Auxiliary Materials: General plastic masterbatch, special coated paper, copier toner raw material
Secondary Reminder: Not suggested as primary colorant for high jet topcoat; without reinforcement performance for rubber compounds.
