MDR Antifouling Paint: Purpose-Built Protection for Your Electronics and Hull

When barnacles and marine growth take hold on your boat's transducer or hull surfaces, the consequences go beyond aesthetics. Antifouling paint is one of the most important tools in a boater's maintenance arsenal — and MDR (Marine Development & Research Corp.) has engineered a highly specialized solution that addresses one of the most overlooked fouling problems on the water: keeping your depth sounder transducer clean and performing at its best.

The MDR Antifouling Transducer Paint (MDR-720)

MDR's flagship antifouling offering is the Anti-Fouling Transducer Paint (MDR-720) — a product designed from the ground up for a very specific and critical application. While most bottom paints protect the hull, the transducer is often left exposed to the same fouling threats. As MDR recognizes, barnacle and marine growth on a transducer is one of the major causes of poor depth sounder performance, making protection here every bit as important as protecting the hull itself.

The MDR-720 formula sets itself apart through its water-based cuprous oxide chemistry. Unlike solvent-based bottom paints, this water-based formula will not attack the transducer face — a critical consideration since aggressive solvents can degrade the sensitive materials used in nylon and bronze transducers. It is compatible with both transom-mount and through-hull transducer styles, making it a versatile choice for a wide range of vessels.

Key Features of MDR Antifouling Paint

• Water-based cuprous oxide formula — effective antifouling action without the risk of solvent damage to transducer materials
• Dual-environment protection — formulated to resist barnacles and marine growth in both fresh and salt water
• Compatible with nylon and bronze transducers — safe for the most common transducer materials on the market
• Brush-in-cap applicator — the convenient built-in brush makes precise application easy, even in tight or awkward locations
• No solvents, easy cleanup — the water-based formula means no harsh chemical cleanup after application
• Below-the-waterline use — engineered specifically for submerged surfaces where fouling pressure is highest

Why MDR's Approach to Antifouling Matters

Most boaters focus their antifouling efforts on the hull and running gear, but a fouled transducer can render your fishfinder or chartplotter nearly useless — a serious safety and fishing performance issue. MDR's targeted antifouling solution plugs this gap with a product that is both safe for sensitive electronics hardware and genuinely effective against biological fouling organisms. The water-based formula also makes it an easier, more user-friendly product to work with compared to traditional solvent-laden marine coatings.

Whether you're a weekend angler maintaining a bass boat or a coastal cruiser keeping a bluewater passage-maker in top shape, MDR's antifouling paint provides a simple, effective layer of defense where it counts.
