ABSTRACT:
An antifoulant patent includes the ingredient of cuprous sulfide or cupric sulfide, both of which offer a hostile surface to chelating algae while retaining a repelling effect on barnacles and mollusks. In one embodiment, the composition comprises from 40 to 75 percent by weight of cuprous sulfide; from 10 to 50 percent by weight of an epoxy resin; from 5 to 25 percent by weight of curing agents; and from 1 to 15 percent by weight of glass fibers. The antifoulant coating results in a colorfast surface and the preferred embodiment has been devised to have a stable black color.
