The present work investigates the use of alloyed zinc powders in zinc epoxy and zinc silicate coatings. It is found that small amounts bismuth have a dramatic effect on rust creep resistance while nickel and magnesium was not found to have any effect in the tested range. 0.5% bismuth in the zinc reduces rust creep by up to 80% after cyclic exposure according to ISO20340. With the alloyed zinc it is possible to formulate zinc epoxy coatings with rust creep below 1 mm in the test, thus achieving performance similar to what is know from zinc silicates.

KEY WORDS: Zinc pigment, Zinc-alloy, Bismuth, Corrosion Protection, Rust Creep, Zinc Silicate
