ProGuard AL (Corrosion Inhibitor ProGuard AL)

ProGuard AL is a concentrated fortified blend of industrial corrosion inhibitors and performance additives that are typically used to boost corrosion inhibitor levels in non-GRAS heat transfer fluids, such as OneGuard AL and other similar products. While ProGuard AL is not an antifreeze, it is compatible with both propylene and ethylene glycol, and glycerin antifreezes without inhibitors or with similar corrosion inhibitor packages. This product not only stabilizes system fluid pH but also offers corrosion protection to typical metallic and non-metallic components used in hydronic systems that contain multi-metals among them aluminum, cast iron, steels, and copper. ProGuard AL has low toxicity profile (essentially non-toxic) courtesy of the relatively low toxicity and levels of the non-GRAS components. As such, it may be registered with the NSF under category code HTX-2.
