Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aqueous dispersion liquid
Liquid polymer dispersions are paints/varnishes, not primary polymers.
If contains surfactants >5%
Preparations with significant non-polymer content classify as mixtures.
If FEP-modified dispersion
Fluorinated ethylene propylene copolymers use separate subheading.
