Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If colorant content >5%
High pigment loading shifts from polymer to synthetic organic coloring matter.
If considered prepared additive binder
Polymer-colorant mixtures exceeding masterbatch specs become chemical preparations.
If acrylic color modifiers predominate
Acrylic polymer color systems classified under Chapter 39 acrylic headings.
