How long can parts be expected to remain free of corrosion after removal from a Zerust / Excor® ICT® package?

0

Tests performed with electron scanning (ESCA) microscopy show that 2-4 hours after a steel test panel is removed from a Zerust / Excor® ICT® package, all traces of the corrosion inhibiting molecular layer are gone from the surface of the part. The period of time before one can expect corrosion to occur on a part depends on the cleanliness of the part and the environment around the part (relative humidity, presence of pollutants or wood, temperature, etc.).
