Impending return of Irgarol 1051 brings back familiar, slime-resistant blends.
We werent too surprised to learn that Irgarol 1051, an antifouling paint additive that last year was awaiting U.S. Environmental Protection Administration certification, has received approval to re-enter the market. As we reported last spring (see Bottom Paint Update 2017, Practical Sailor April 2017), Irgarol 1051s manufacturer, BASF, had moved its manufacturing to Asia, and was waiting for its new foreign-sourced formula to be certified by the EPA. By 2016, nearly all of the major antifouling paint manufacturers in the U.S. had exhausted their reserves. Now Irgarol is back, which means there may be some confusion as to what secret sauce is boosting the performance of your top-shelf slime-resistant paint.
