Note:The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.
For maximum tinting strength, disperse the pigment with high-shear milling (e.g., bead milling) using a suitable dispersant for your system. Start with low pigment loading and test incremental additions; because IOB-722 has high tinting power, small changes in concentration significantly affect final shade.
IOB-722 is inherently UV-stable compared to many organic blacks, but final weathering resistance depends on the binder and additives. For outdoor applications, combine with UV absorbers and light stabilizers to further enhance service life.
Provide a spectrophotometer reading (L*a*b*) of the target sample. We can suggest a lab recipe, but shade adjustment often uses small additions of titanium dioxide or iron oxide red/yellow to warm or cool the black. Maintain strict batch control for particle size distribution to reduce inter-batch variability.
We offer TDS, SDS, and QC certificates on request. Sample policy: typical small samples are available; for larger lab or production trials, we provide paid samples or bulk sample packs—contact our sales team with intended application details.
