S-76 Tack Coat Primer is for use on properly prepared steel, aluminum or
galvanized steel. S-76 is an anti-corrosive strontium chromate based primer
that is specifically designed for underwater metal surfaces including hulls,
running gear, and the lower units of outboards and I/O’s. It provides an
excellent barrier to reduce pitting of the metal from galvanic corrosion.
This product may be used on bare aluminum in conjunction with Tuff Stuff High Build Epoxy to form a barrier for application of copper-based antifoulants.
