USE:

Phosphoric acid etch and brightener. Will not drain from vertical or inverted surfaces. Alternate to E-2310.

An exclusive formula, all-purpose brush-on, wash-off cream cleaner, brightener, and paint preparation for all aluminum surfaces. Will clean and remove light oil, natural oxides, weathering stains, and light corrosion while etching to provide a firm primer bond. Restores new alumi-num appearance. Non-flammable.

INSTRUCTIONS:

Surfaces heavily coated with oil, dirt, or mud should be cleaned with 1 part 310 Alkaline Cleaner in 20 parts water. After alkaline cleaning, mask any adjacent areas which may be damaged by acid contact, using cloth masking tape and polyethylene plastic sheet. Working a limited area to provide adequate attention, apply the cream to a thickness of approximately 1/16" with a nylon or polyester brush or synthetic sponge. Use a plastic, porcelain or stainless steel container. Continue working the surface to replenish spent cream and obtain uniform brightening. Chemical action will be noted by slight foaming which will stop when cream is spent. Keep the surface coated for 1 to 5 minutes depending on the degree of cleaning, etching, or brightening action required. Excessively oxidized, stained, corroded or pitted surfaces should be scrubbed with Scotch-Brite ultra-fine cleaning pads while etching.

Rinse with clean running water while wiping with clean rags or a sponge. Do not rinse with hot water. Any acid remaining around rivet heads or seams can cause primer failure. Air blow hinges, seams, or points which may trap acid.

Allow surface to dry, or wipe dry with clean rags and proceed with next operation within eight hours. We recommend Aluma-Dyne E-2300 chromic acid treatment for corrosion resistance whether the surface will remain bare, be waxed, or paint-ed with a clear or opaque finish.
