Cortec develops nano VpCI-powered devices for multi-metal corrosion protection

11-09-2020

Cortec has developed vapour phase corrosion inhibitors (VpCI) devices to protect metal by conditioning enclosed environments with corrosion inhibiting vapour molecules. Molecules are attached to and absorb onto metallic surfaces, resulting in the formulation of nanofilms, thin microscopic molecular layers of corrosion protection.

According to Cortec, these devices do not adversely affect or alter the appearance, conductivity, mechanical integrity, or optical functionality of the components protected. Emitted devices are environmentally responsible, economical and compact.

For instance, the EcoEmitter is a biodegradable device designed to provide corrosion protection for sensitive assets such as electronic and optical equipment and components. VpCI’s emit from device and saturate the enclosure via diffusion, filling all void spaces and recessed areas with protective vapour molecules. The design of EcoEmitter uses polymeric cup to replace polyethylene, and is constructed from resins containing 60-80% renewable carbon content. The breathable membrane that emits VpCI is constructed from bio-based fibres.

Another sustainable option is BioPad, Cortec’s flexible corrosion inhibiting device constructed from bio-based non-woven material. It can be employed as a packaging option for corrosion inhibition. Its VpCI concentration, in combination with a thin design, results in material reduction by up to 94% in comparison to similar polyurethane foam emitting devices.

Cortec also have in its portfolio the EcoDevice that is designed to provide corrosion protection for small enclosures such as tool boxes, control panels, electrical cabinets, instruments, and other electronic enclosures. Constructed from bio-based fibres, each EcoDevice protects up to 42 litres, and can be used in polluted and humid environments.
