Natural iron oxide pigment is not suitable for the solution vinyl resin, which could cause gel or discolor in the inks and coatings.

However, when the iron oxide pigment is the necessities for the formulations,please choose synthetic iron oxide and add heat stabilizer at the same time.

It is prohibited to use alkaline-based pigment and filler for carboxyl-modified vinyl resin, especially the pigment containing metal lead zinc powder, zinc oxide, strontium-contained and calcium carbonate, or the deviation on the viscosity of the solution will happen and cause irreversible gel.
