SAF-T-EZE Regular Grade Anti-Seize is a smooth non-separating formula consisting of lithium soap thickened grease into which is compounded very fine flaked copper, as well as graphite lubricants and corrosion fighting inhibitors. The high performance grease and solid additives provide extreme pressure lubricating properties that prevent galling and cold welding and at the same time prevents water wash out and galvanic pitting from electrolysis of road salt, acid rain, or salt water.The properties of SAF-T-EZE Pure Copper Grade Anti-Seize are similar to the Regular Anti-Seize but without the aluminum present. The copper color is apparent.
