 Sacrificial Galvanic Action? |
To celebrate Issue #666 we rerun our article on Type CG™ Cold Galvanizing Spray. This wonderful product has absolutely nothing to do with satanic worship or the mark of the beast, but people sometimes wonder ... Polywater's claim that its Type CG aerosol "prevents rust and inhibits corrosion through sacrificial galvanic action" often evokes images of druidic weirdness and prompts agents to say, "Sacrificial what?" Galvanizing is the process of dipping steel in hot, molten zinc. Zinc oxidizes (rusts) much more slowly, less destructively, and less visually (silvery-white) than steel. The result is a metal coating that bonds better, looks good longer, and protects steel better than paint. Since "hot-dipping" is not very practical in the field, the next best thing was developed: cold galvanizing. This is essentially spray paint with zinc added. It's portable, inexpensive, easy to apply, looks like silver paint, and offers the sacrificial zinc protection. It's not quite as effective as hot zinc galvanizing, but is definitely superior to normal paint. In essence, the zinc coats the surface, sacrificing itself on Mother Nature's alter by rusting, and protects the critical metal parts beneath. Think of it as "metallic martyrdom." Virgins are optional. |
