Loctite LB 8012 contains 65% molybdenum disulfide for maximum lubricity. It is a heavy, black paste with unsurpassed lubricating qualities. Machine tool marks and other irregularities are reduced to a mirror-smooth finish by its lubricating action. Loctite LB 8012 reduces friction on threaded fasteners, including bolts, nuts and studs. The low and uniform friction coefficient of 0.06 creates reliable assembly conditions. Lubricant stays in place through heat, load and vibration to ensure a trouble-free disassembly.
