Interlux Micron CSC Ablative Bottom Paint

Micron CSC multi season ablative paint provides a controlled release of anti-fouling biocide at the paint surface and will not lose its effectiveness when the boat is hauled out of the water for extended periods of time. A superior marine anti-fouling bottom paint.

Why is Micron CSC so popular? Interlux Micron CSC is suitable for power boats , sailboats, and uses Micron Technology to provide excellent, long lasting antifouling protection against all types of fouling. Polishing occurs at a controlled rate, similar to how a bar of soap wears down, but at a much slower rate. Micron CSC reduces buildup of old coatings, minimizes sanding, and allows the boat to be hauled and relaunched the following season without repainting. If you want superior antifouling protection against algae, weeds, barnacles, and other shell fouling Micron CSC is your go to paint. Micron CSC can be used below the waterline in fresh, salt or brackish water on fiberglass, wood and properly primed metal boat hulls and parts. Not for use on aluminum. This product dries to bright colors. 

With a higher solids content than Micron Extra, Micron CSC is harder and wears away at a slower rate but just like other paints in the Micron line offers the advantages of controlled polishing which reduces buildup of old coatings and minimizes the need to sand at reapplication. Uses less copper more efficiently than high-copper, hard-antifouling paints. Can be hauled and relaunched without loss of effectiveness. Suitable for all boats in all waters.
