Interlux Paint Antifouling Paint

Interlux Antifouling Paint: Decades of Hull Protection Innovation

Interlux Paint has been a cornerstone of marine hull protection for well over a century, and nowhere is that expertise more evident than in their lineup of antifouling bottom paints. With 35 products spanning hard, ablative, and hybrid formulations, Interlux gives boaters the tools to fight back against barnacles, slime, weeds, and zebra mussels in salt, fresh, and brackish water alike.

Proprietary Technologies That Set Interlux Apart

What distinguishes Interlux in the antifouling category is the depth of its proprietary technology. Biolux® Slime Blocking Technology is an exclusive Interlux innovation woven into many of their formulas — it specifically targets slime and algae that standard copper-based paints often miss. Paired with Biolux, Interlux leverages Econea™, a copper-free biocide that wards off barnacles and zebra mussels without the galvanic corrosion risks associated with cuprous oxide, making it ideal for aluminum hulls and outdrives.

Flagship Product Lines

The Micron Series is the crown jewel of Interlux's antifouling lineup. Micron CSC is a self-polishing ablative that behaves like a bar of soap — it polishes and becomes smoother with each use, which reduces drag, improves fuel efficiency, and minimizes paint buildup over time. The Micron CF takes that further by adding Biolux® Slime Blocking Technology and Econea™ in a high-solids, VOC-compliant formulation rated for use on all boats in all waters.

For boaters who want the best of both worlds, Fiberglass Bottomkote NT uses a unique Dual Resin Technology that combines the benefits of both ablative and hard antifouling paints in a single coat — and its fast-dry formula means you can paint and launch on the same day. The Bottomkote ACT builds on this with dedicated Ablative Technology that erodes cleanly with use, eliminating the need for heavy sanding between seasons.

Copper-free boaters will find a reliable solution in Pacifica Plus, a dual-biocide ablative that uses up to 80% less active biocide ingredients than comparable antifouling paints while still delivering high-performance protection in fresh, salt, and brackish water. For aluminum-specific applications, Trilux® 33 replaces cuprous oxide with the safer cuprous thiocyanate and pairs it with Biolux to control both shell fouling and slime growth.

Choosing the Right Interlux Antifouling Paint

Selecting the right formula depends on your hull material, water type, how often your boat is in the water, and your regional fouling pressure. Hard paints like Trilux 33 excel in high-traffic trailered boats, while polishing ablatives like Micron CSC reward year-round boaters with a self-renewing surface that actually improves with time. Interlux's broad range ensures there is a purpose-built solution whether you own a fiberglass sailboat, a high-performance powerboat, or an aluminum-hulled vessel.
