Description
Pettit Aluma Protect Epoxy Barrier Coat Marine Primer For Aluminum Hulls

Aluma Protect 4400/4401 is a 2 part strontium chromate primer designed to form the ideal barrier coat over roughed bare aluminum. This is the appropriate epoxy to use when aluminum has been sandblasted, sanded or ground so that a tooth is present. For smooth aluminum, choose Pettit Metal Primer 6455/044.

AlumaProtect provides maximum resistance to fresh or salt water, thus eliminating corrosion. This complete coating system resists water, industrial chemical fumes, and very humid environments. Intended to be used as a primary coat over bare aluminum hulls and outdrives. AlumaProtect 4400/4401 will chalk if not topcoated. Two coats are recommended over sandblasted aluminum. Then overcoat with Pettit Protect 4700/4701 for optimum results before finishing antifouling paint.

  • Epoxy Primer for Aluminum
  • Strontium Chromate for Maximum Corrosion Control
  • Easy to Apply and Excellent Bonding Surface

*If these recommended intervals are exceeded, sand thoroughly with 80 grit sandpaper before recoating or applying bottom paint.

PREVIOUSLY PAINTED SURFACES: Aluma Protect Aluminum Epoxy Primer 4400/4401 may be applied over existing two part epoxy fi nishes, provided they are in sound condition. Brush-off sandblasting or very heavy sanding with 60 grit sandpaper is required to maintain maximum adhesion. Then apply one or two coats 4400/4401 per instructions. Remember, coating performance is only as good as the surface to which it’s applied. All existing two package epoxy fi nishes in poor condition, as well as all one package primers and bottom paints, should be removed completely and the appropriate bare aluminum system as described above should be followed before using Aluma Protect Aluminum Epoxy Primer 4400/4401. Aluma Protect Aluminum Epoxy Primer is not recommended for use over antifouling paints.

STEEL HULLS: Not recommended - use Pettit Protect 4700/4701 for steel surfaces.

ALUMINUM: Sandblast (using non-metallic media) or disc sand the aluminum to clean, bright metal. Wipe clean of residue and immediately apply one coat of Aluma Protect Aluminum Epoxy Primer 4400/4401. At 70°F let dry 4 hours minimum, 96 hours maximum, and apply an additional coat followed by two coats of Pettit Protect High Build Epoxy Primer 4700/4701 following application and recoat instructions.

APPLICATION INFORMATION: Stir both components thoroughly. Mix the two components together in the ratio of 1 part of Component A to 1 part of Component B by volume. Allow to stand 15 minutes at approximately 70° before using. (Allow to stand at least 30 minutes if temperature is between 50° and 65°F) May be applied by brush, roller, conventional or airless spray. Thinning is not normally required for application, however, small amounts of 97 Epoxy Thinner may be used if necessary to facilitate application. Wet fi lm thickness should be 3.6 mils per coat, which yields 1.0 mil dry fi lm thickness. A wet fi lm thickness gauge should be used to monitor paint application. One or two coats of Aluma Protect 4400/4401 should be overcoated with Pettit Protect 4700/4701 to provide a corrosion and chemical resistant barrier for use on all aluminum craft and surfaces. Coating performance, in general, is proportional to the degree of surface preparation. Follow recommendations carefully, avoiding shortcuts. Inadequate preparation of surfaces will virtually assure inadequate coating performance. Degrease aluminum by wiping with 97 Epoxy Thinner. Sandblast, sand or grind the surface to achieve a good adhesion profi le.
