Antifouling F129

Q. I want to know if I can use the same cuprous oxide as in F121. So I can use with black iron oxide to obtain a dark brown color.

A. We are not familiar with your formula F121, but we are familiar with oxide pigments. Combining cuprous oxide and black iron oxide will produce a dark brown color depending on the ratio of one pigment to another. You may also consider tinting with red iron oxide to enrich the final color.
