SC-21 is an ultra-thin, super slick, low friction paint film for boat bottoms. It is the ideal racing finish for fresh water boats. SC-21 combines copper-bronze powder, Moly-Disulfide, and PTFE to produce a super-slick paint film that reduces surface friction allowing the hull to slide through the water. SC-21 is recommended for use on fiberglass, wood and properly primed steel boats. It is easy to apply and dries in 15 minutes. Color changes upon immersion.

Important highlights:

  • SC-21 is designed to provide a similar performance to our 1959 Copper Bronze Racing Finish, but with a much slicker paint film
  • SC-21 comes in the same container packaging as several of our two-part paint products, with two cans clipped together
  • The top can contains a pouch with a proprietary blend of copper-bronze powder along with highly refined slickening agents
  • The slickening agents use in SC-21 are copper-bronze powder, Moly-Disulphide, and PTFE
  • The applicator will add the pouch (located in the top can) to the product prior to application
  • SC-21 will provide the same or better racing performance as other popular products on the market
  • SC-21 Makes a great replacement for VC-17 and SR-21 as they are 100% compatible
SC-21 is intended for use as a non-antifouling product to be used as a replacement for SR-21 until Irgarol becomes available again. SC-21 uses the same part number and UPC Code as the SR-21 product.
