Frequently Asked Questions

Is Iron Oxide Red Y101 the same as Pigment Red 101?

Yes — Iron Oxide Red Y101 refers to a red iron oxide pigment commonly categorized as Pigment Red 101 in the color index. Our Y101 formulation is optimized for high tint strength and weather fastness.

Which dispersants/work-up work best for plastics?

For polyolefins use grafted maleic anhydride compatibilizers or high shear masterbatching. For PVC, standard wetting agents and lubricants assist dispersion. Trial blending is recommended to determine optimum loading and dispersant level.

Can this pigment be used outdoors without fading?

Yes — Iron oxide pigments, including Y101, are inorganic and generally exhibit excellent light and weather fastness compared to organic pigments. Performance depends on the binder and formulation used.
