CORRGUARD™ EXT is a multifunctional additive that helps enable formulation of longer-lasting metalworking fluids with improved pH stability, excellent corrosion control of ferrous metals, multi-metal compatibility and resistance to extraction by tramp oil. CORRGUARD EXT has been shown to provide enhanced fluid life when used with a broad range of registered biocides, offering formulators an ideal solution to optimize the performance of their existing fluids without requiring significant reformulation. It also offers a favorable environmental profile and is readily biodegradable in the environment.
