NEI Corp.’s Nanomyte PT-60C is a chromate-free conversion coating designed to provide corrosion resistance to lightweight metal alloys such as aluminum and magnesium used in the electronics industry, while simultaneously providing surface and bulk electrical conductivity.

NEI Corp.’s Nanomyte PT-60C is a chromate-free conversion coating designed to provide corrosion resistance to lightweight metal alloys such as aluminum and magnesium used in the electronics industry, while simultaneously providing surface and bulk electrical conductivity. The waterborne coating’s “self-repairing” nature is said to overwhelm the galvanic corrosion caused by its electrical conductivity.

Coatings on lightweight metal components get damaged over time due to contact and spring impact, and the damaged areas are sites of potential galvanic and general corrosion. In order to maintain electrical conductivity in grounding and electromagnetic interference shielding, corrosion in the contact areas needs to be inhibited, NEI says.

Applications of PT-60C include places where metallic chassis, cases and frames protect electronic circuitry and sensitive LCD displays, including CD/DVD/Blu-ray players, smartphones, digital camera housings, cell phones, computer notebooks bases and handheld devices.
