Zinc dust is a fine, reactive powder of elemental zinc, primarily used in galvanization, metallurgy, and as a reducing agent in chemical synthesis. It is also applied in pyrotechnics, batteries, and zinc-rich anticorrosive primers. This ultra-fine powder has a CAS number of 7440-66-6, a molecular weight of 65.39 g/mol, and requires ambient storage. It carries a Danger signal word due to its high reactivity and flammability. Molekula supplies zinc dust from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
