Abstract

Cuprous oxide is one of the most commonly employed antifouling pigments. However, its red color limits further pigmentation of the paint. On the other hand, cuprous thiocyanate is a white pigment that can be employed when film pigmentation in other colors is required. The purpose of this paper is to study the chemical and biocidal properties of cuprous thiocyanate, in comparison with those of cuprous oxide, with a view of its utilization in paint elaboration.

The solubility, oxidability, particle size distribution, and oil absorption of the pigment were determined along with two methods for its preparation. A solubilization mechanism for cuprous thiocyanate is also outlined.

Biological tests were carried out in the laboratory in order to evaluate the biocidal properties of cuprous thiocyanate. Lt50 and Lt100 were determined for Balanus amphitrite nauplii and cyprids.

White cuprous thiocyanate has, in many ways, similar properties to those of cuprous oxide, although it is less oxidizable and has a greater lethal action than cuprous oxide.
