Zinc powder, -100 mesh, 97+%, Thermo Scientific Chemicals

Description

Zinc powder is used in thermal spraying for corrosion protection and in the chemical industry. It provides chemical potential energy in alkaline batteries to pump electrical charges between the negative and positive terminals. It is used as a fuel for model rockets with a mixture of 2.04 parts zinc to one part sulfur. It is used as protective pigment in industrial coatings, as a reducing agent and catalyst in a variety of chemical reactions.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
