Manufacturer

Interlux Paint

<p>Since 1881, Interlux has established itself as one of the world's leading manufacturers of high-performance marine coatings and yacht finishes. As a division of AkzoNobel, Interlux combines over a century of expertise with cutting-edge coating technology to deliver protection and beauty for vessels of all sizes, from recreational powerboats to racing sailboats and luxury yachts.</p><h3>Marine Coating Excellence</h3><p>Interlux's reputation is built on formulating specialized solutions that address the unique challenges of the marine environment. Unlike automotive or general-purpose coatings, marine paints must withstand constant exposure to UV radiation, saltwater, temperature fluctuations, and the physical stresses of wave action. Every product in the Interlux lineup is engineered specifically for marine applications, ensuring vessels receive the protection they need while maintaining a brilliant, professional appearance.</p><h3>Comprehensive Protection Systems</h3><p>The Interlux product range covers every aspect of vessel maintenance and refinishing. Their <a href="/7399-interlux-paint-wood-finishes-varnish-201205">wood finishes and varnishes</a> preserve and enhance natural teak and other marine woods with UV-resistant formulations that withstand harsh sun exposure. For hull and deck applications, <a href="/7399-interlux-paint-interlux-topside-paint-200585">topside paints</a> deliver durable, high-gloss finishes that resist chalking and fading season after season.</p><p>Below the waterline, protection becomes even more critical. <a href="/7399-interlux-paint-interlux-antifouling-paint-200583">Antifouling paints</a> prevent the growth of barnacles, weeds, and slime that can degrade hull performance and increase fuel consumption. For competitive sailors, <a href="/7399-interlux-paint-interlux-racing-bottom-paint-200584">racing bottom paints</a> are formulated to maintain smooth, low-friction surfaces that maximize speed through the water.</p><p>Proper surface preparation is essential for long-lasting results, which is why Interlux offers a complete line of <a href="/7399-interlux-paint-primers-sealers-200811">primers and sealers</a> that ensure optimal adhesion, prevent corrosion, and create the ideal foundation for topcoats. These barrier coats and anti-corrosive primers are critical for protecting fiberglass, wood, and metal surfaces from water absorption and galvanic corrosion.</p><h3>Innovation and Performance</h3><p>Interlux continues to advance marine coating technology with innovative formulations. Products like Brightside polyurethane enamel and two-part Perfection paint deliver durable, high-gloss finishes, while ablative bottom paints use self-polishing technology that continuously renews the active surface. Whether refinishing a classic wooden yacht or maintaining a modern performance cruiser, Interlux provides the coating solutions that professional boatyards and knowledgeable boat owners trust for exceptional results.</p>

Product Details

Interlux Ultra-Kote Y3669U/1 is a premium hard antifouling bottom paint designed to deliver excellent long-term protection against marine growth in medium to high fouling environments. This professional-grade marine coating features a fast-drying formula that creates a durable, scrubbable finish ideal for both power and sail boats.

Key Features:

  • Premium fast-drying hard antifouling formula provides season-long protection against barnacles, algae, and marine growth
  • Durable, scrubbable finish withstands cleaning and maintains performance throughout the season
  • Excellent color stability resists fading from UV exposure and maintains attractive blue appearance
  • VOC compliant formulation meets environmental regulations for marine coatings
  • Boatyard and applicator friendly with compatibility across most antifouling paint systems
  • Suitable for use on fiberglass, wood, and properly prepared metal surfaces

Ultra-Kote's hard finish technology makes it an ideal choice for boats stored on trailers or in areas where the bottom may be scrubbed during the season. The fast-drying properties reduce haul-out time, while the durable formulation provides reliable antifouling performance in challenging marine environments. Each gallon provides approximately 400 square feet of coverage per coat, depending on surface conditions and application method.

Note: This product is sold as a 2-gallon case (2 x 1-gallon containers) and ships as Blue color (Y3669U/1).
