Wurth CU 800 is a high temperature and high pressure resistant adhesive lubricant. It is the corrosion protecting copper paste that we use on all battery busbar connections as well as many of our other conductive lubrication needs. Only the very smallest amount needs be applied to bolts and threaded connections to ensure prevention of seizing, fusing, baking, corrosion and wear. In addition to battery terminal and connection applications it can be used on brake pins, sliders, wheel studs, bolts, nuts and most threaded fasteners. It can also be used for applications where assembly and reassembly is required. Wurth CU800 Copper Anti-Seize prevents seizure in bolts. Wurth CU800 Copper Anti-Seize will not harden and crumble. Temperature resistant up to +1200 Degrees Celsius (2192 Degrees Fahrenheit) 1 Jar is enough paste for up to 3 conversions. Material: Copper Paste Quantity: Job Size .75 oz
