Many of the corrosion resistant greases on the market are petroleum base oils thickened with 3% to 9% soap. The soaps are typically lithium, aluminum and anhydrous calcium and the resulting grease is treated with 2-5% rust inhibitor. The rust inhibitor is oil soluble and surface active, wanting to wet out on the steel surface. Over a time, the oil separates and the low additive content depletes. KORR-GUARD actually complexes the rust inhibitor in high quantity as a component in the thickener. The thickener holds the rust inhibitor in place so additive depletion becomes a less significant factor in long term storage.
Protective grease-like coating to protect equipment and threaded pipe ends against rust and corrosion. Not recommended for use as a thread compound.
