US-based Cortec Corporation has launched Cor-Pak Tablets – a new and “extremely efficient” dry anti-corrosion method for protecting metals within a package.
Using Cortec’s Vapor phase Corrosion Inhibitor (VpCI) technology, Cor-Pak Tablets are said to eliminate the need for costly conventional methods of applying and removing coatings.
VpCi works through an ionic action to create a molecular, corrosion inhibiting layer on metal surfaces.
Cor-Pak Tablets are designed to protect products, components, or assemblies when packaged in corrugated boxes, plastic wrap or bags, and metal, plastic, or wood containers.
According to the Minnesota-based technology company, just a few tablets need to be dropped into a bag, box, or package.
“After the VpCI vapourizes, it will attach to all metal surfaces, reaching even recessed areas,” Cortec says.
“The protective monomolecular layer does not need to be removed prior to processing or operation.”
If the protective layer is disturbed by a package being opened, it will be replenished by continuous vapour protection upon reclosing.
The VpCI layer does not interfere with the operation of electrical and electronic components.
“They will also protect from salt water during overseas transport,” the company says. “Protected parts can be used immediately.”
Cor-Pak Tablets are nitrite, phosphate, and silicate free, and each one will protect up to 7.1 litres of enclosed space.
They can be easily inserted in packaging by manual or automated systems, with no spraying, wiping, dipping, surface preparation or regeneration required.
