Henkel 39901 LOCTITE® LB 8044™ Gray Zinc Anti-Seize - 453.6 Gram (1 lb) Can

Loctite Zinc Anti-Seize (formerly C-638) is a smooth, homogenous mixture of zinc dust and petrolatum. It prevents seizing during assembly or disassembly of threaded or unthreaded metal joints--particuarly if these metal joints involve aluminum or aluminum alloys. Zinc Anti-Seize also provides corrosion protection for both aluminum and ferrous metal (iron Base) components. Within a metal threaded connection, it acts like an "internal galvanize" using the electrochemical properties of the zinc dust to protect iron surfaces.
