Hello,
I am an R&D scientist for Mankiewicz coating in Charleston SC. We are looking for antifouling additives for marine applications that are used legally for 2K polyurethane top clear coats that can help protect underwater surfaces of boat from bacteria, algae. etc. Our main concern is that antifouling additives should be compatible with high gloss clear coat and do not cause haziness. We prefer a liquid form, but powder should be also good as long as it is compatible with high gloss topcoat. I would appreciate it if you can recommend me some options.
