Interlux Paint Micron CSC Antifouling Bottom Paint

Interlux Micron CSC Antifouling Bottom Paint

Interlux Micron CSC is a premium self-polishing ablative bottom paint that delivers long-lasting, multi-season protection against marine fouling. Using Micron Technology, this copper-copolymer formula slowly wears away in a controlled way as the boat moves, continually exposing fresh biocide at the surface. That means reliable antifouling performance in fresh, salt, and brackish water without the heavy paint build-up and aggressive sanding associated with many hard bottom paints.

Micron CSC is suitable for both powerboats and sailboats and can be used on fiberglass, wood, and properly primed steel or lead below the waterline. It is not recommended for aluminum hulls or underwater aluminum components. Available in a range of popular colors, it’s one of the most trusted choices for boaters who want proven, easy-to-maintain multi-season protection.

Best Uses

Multi-season antifouling protection for powerboats and sailboats

Boats that stay in fresh, salt, or brackish water for extended periods

Owners who want an ablative coating that minimizes bottom paint build-up and sanding at recoat time

Boats that are hauled for winter storage and relaunched the following season

Fiberglass, wood, and properly primed steel or lead hulls below the waterline (not suitable for aluminum)

Key Features & Benefits

Multi-season ablative protection: Micron Technology provides long-lasting defense against a wide range of fouling in all water types when applied at the recommended film thickness.

Copper-copolymer formula: Uses a controlled-solubility copolymer with cuprous oxide to maintain an active biocide layer at the paint surface throughout the season.

Self-polishing, low build-up: The coating gradually erodes in a controlled way, like a bar of soap, helping prevent excessive paint build-up and reducing the amount of sanding needed at recoat.

Haul and relaunch flexibility: Micron CSC can be hauled for storage and relaunched later without losing effectiveness, provided the film is in good condition and properly cleaned before going back in the water.

Smoother, more efficient hull: The polishing action helps the bottom remain smooth, which can improve speed and fuel efficiency compared to rough or heavily built-up coatings.

Versatile application: Can be applied by brush, roller, or spray over most existing antifouling paints that are in sound condition, following the Interlux compatibility guidelines.

Application & System Overview

Micron CSC can be applied over most well-adhered antifouling coatings or directly to properly prepared bare substrates as part of an Interlux paint system. Always read the product label and technical datasheet before starting a job.

Substrates: Fiberglass, wood, and properly primed steel or lead below the waterline (not for aluminum hulls or drives).

Existing antifouling: Confirm compatibility with the Interlux antifouling compatibility chart. The existing paint must be aged, tightly adhered, and in good condition.

Coats: Typically 2–3 full coats are recommended, with an extra stripe coat on high-wear areas such as the waterline, chines, rudders, and leading edges.

Methods: Apply by brush, roller, or spray using equipment suitable for solvent-based bottom paints, following all safety and ventilation guidelines.

Always stir or shake Micron CSC thoroughly before and during application to keep the copper and resins evenly distributed in the can.

Surface Preparation Overview

Good surface preparation is essential for maximum performance and adhesion. The steps below are a general overview; always follow the detailed instructions on the Micron CSC label and technical datasheet.

Previously painted surfaces – in good condition

Scrub the bottom to remove slime, salts, and loose growth, then rinse and allow to dry.

Lightly sand with the recommended grit if required to create a smooth, dull surface.
