摘要

The composition of small partu00ecculas copper pyrithione, the pesticidal paint, method for increasing the effectiveness of anti fouling of an ink composition of a dispersion of copper pyrithione not forming powder, method for preparing a dispersion not forming powder, method for a In the caracteru00ecsticas anti fouling of a paint.Method for aumemtar the leaching rate of copper pyrithione an ink.It is described a composition comprising a dispersion of copper pyrithione not forming powder, comprising small solid particles of pyrithione dispersed in a dispersant copper liquid, said solid particles having a particle size in the range from about 0.1 to about 10 microns and an average particle size of 0.2 to less than 0.5 microns.The dispersion is appropriately used as the additive for anti fouling paint sea, without risk of exposure of the operator to the powder of copper pyrithione. Paints containing small particles of copper pyrithione exhibit antifouling performance improved in cold water, as compared with inks containing larger particles of copper pyrithione.
