S-76 Tack Coat Primer™
S-76 Tack Coat Primer™ is for use on properly prepared steel, aluminum or galvanized steel. S-76 is an anticorrosive primer that is specifically designed for under-water 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. S-76 should be used in conjunction with another primer such as Tuff Stuff prior to applying antifoulant/topcoat.

- Application
When over coating S-76 Tack Coat Primer, it is important to meet the required over coating times in order to achieve the best adhesion because temperature and humidity control dry times. It is hard to give exact times of cure. An easier rule in epoxies is when the coating is dry to the touch, yet still has some tack; it is ready to be over coated. However, if the coating has been fully cured for longer than 5 days, it needs to be thoroughly sanded with 80 grit sand paper to remove shine. If the coating is not sanded after 5 days of full cure, application of additional primers will not adhere.
- Limitations
Apply in good weather when air and surface temperatures are above 50°F (10°C). Surface temperature must be a least 5°F (1°C) above dew point. For optimum application properties, bring material to 70-80°F (21-27°C) temperature range prior to mixing and application. Unmixed material (in closed containers) should be maintained in protected storage between 40° and 100°F (4-38°C). Prolonged atmospheric exposure of this product may detract from performance.
