Primocon Gal - (MW)
Interlux Primocon Underwater Marine Primer
Primacon is an anti-corrosive primer for all underwater metal surfaces. It will provide an excellent barrier to reduce pitting caused by galvanic corrosion. For non-aluminum underwater metal use any (non-vinyl_ Interlux antifouling paint. An excellent primer for antifouling paint over sanded fiberglass. Primocon can be used as a conversion coating over unknown well-adhered antifouling paint to prevent cracking of new antifouling paint. Primocon will not affect the color of antifouling paint.

Note: Do not overcoat Primocon* with VC Offshore, Baltoplate, VC 17m, VC 17m Extra or 2-part epoxies.
PREVIOUSLY PAINTED SURFACES: Sand with 80 grade (grit) paper. Wipe down with Brush-Ease 433 or Special Thinner 216 to remove sanding residue.
BARE METAL: Surface should be blasted to bright metal. For steel surfaces, grit blasting is preferred. For aluminum or other light alloys, sandblast if possible or grind with medium coarse grade (grit) emery cloth. Remove all blasting/grinding/sanding residues with a clean air line and sweep with a clean brush or broom. (Vacuum clean for best results.) Do not wipe with cloth rages after blasting or sanding as fibers may be pulled out and protrude through the primer coats.
APPLICATION INFORMATION: Apply a minimum of 3 coats of Primocon*. Primocon* may be applied directly to blasted metals if applied within 1 hour after blasting. If sanded or if more than 1 hour has passed since blasting, prime bare metal with self-etching primer. Airless Spray Pressure: 170-204 bar/2500-3000 psi. Tip Size: 0.53 mm/21 thou. Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 1.5-1.8 mm/60-70 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.8-2.2 mm/70-85 thou. When spraying with Siphon Cup equipment, reduce first with Special Thinner 216. Other Apply extra coats of Primocon* over riveted or welded areas. Do not sand between coats of Primocon* or between last coat of primer and first coat of antifouling. There is no maximum overcoating time between coats of Primocon* or between the last coat of primer and the first coat of antifouling paint. It is, however, suggested that after thirty days the surface is sanded and wiped clean before proceeding. Product temperature should be minimum 10°C/50°F and maximum 29°C/85°F. Ambient temperature should be minimum 10° C/50°F and maximum 35°C/95°F. Substrate temperature should be minimum 10°C/50°F and maximum 29°C/85°F. Primocon* prevents leaching of TBT from an underlying antifouling coating provided it is applied at a minimumdry film thickness of 3.5 mils (minimum of 2 coats by roller) & that the film remains intact. We have studied the leaching rate of TBT from a TBT SPC antifouling (such as Micron 44) overcoated with Primocon* (applied as specified) & seen that TBT leaching is prevented. The leaching rate determination method used was ASTM D5108-90 (2002) Standard Test Method for Organotin Release Rates of Antifouling Coating Systems in Sea Water. Do not use under vinyl based antifouling paints such as VC Offshore.
Frequently Asked Questions
What is Interlux Primocon Underwater Marine Primer used for?
Interlux Primocon Underwater Marine Primer is an anticorrosive primer for underwater metal surfaces, including hulls, running gear, and outboard or I/O lower units. It also can be used as a primer for antifouling paint over sanded fiberglass and as a conversion coating over unknown, well-adhered antifouling paint.
Can Interlux Primocon be used on underwater metal surfaces?
Yes. Primocon is designed for underwater metal surfaces and provides a barrier intended to reduce pitting caused by galvanic corrosion. For bare metal, the surface should be prepared to bright metal before application. Primocon may be applied directly to blasted metal when applied within 1 hour of blasting.
How many coats of Interlux Primocon should be applied?
Apply a minimum of 3 coats of Interlux Primocon, with 3-4 coats recommended as needed. Extra coats should be applied over riveted or welded areas. Do not sand between Primocon coats or between the final primer coat and the first coat of antifouling paint.
What application methods can be used with Interlux Primocon?
Interlux Primocon can be applied by brush, roller, airless spray, or conventional spray using pressure-pot or siphon-cup equipment. The product provides approximately 300 square feet per gallon of coverage, although the stated coverage varies by application method.
What temperature is recommended for applying Interlux Primocon?
Apply Interlux Primocon when the ambient temperature is between 50°F and 95°F. Product and substrate temperatures should be between 50°F and 85°F. At 73°F, Primocon takes approximately 2 hours to become touch dry and 5 hours before recoating.
Can Interlux Primocon be applied under any antifouling paint?
Primocon can be used with non-vinyl Interlux antifouling paints, but it should not be overcoated with VC Offshore, Baltoplate, VC 17m, VC 17m Extra, or 2-part epoxies. It also should not be used under vinyl-based antifouling paints such as VC Offshore.
