VPCI® Powder Products

What Are VpCI® Powders?

VpCI®s protect metals electrochemically.

Corrosive agents attack metals at every opportunity – especially in crevices, cavities and voids where paints and coatings are rendered useless. Now there is a way to defend against corrosion at a molecular level – Vapor phase Corrosion Inhibiting (VpCI®) powders from Cortec® Corporation.

Cortec® VpCI® powders shield metals unlike any other protective substance. Cortec® manufactures VpCI® powders with moderate vapor pressure so they volatilize easily. VpCI® powders sublime directly to a vapor that seals metals with a chemically adsorbed monomolecular film.

Why Are VpCI® Powers Used?

Immediate results. Constant protection.

VpCI® powders stop the corrosion process electrochemically. Application is easy, with little or no surface preparation required. Cortec VpCI® even prevents further corrosion of previously corroded, painted or coated surfaces.

Once applied, Cortec powders protect both ferrous and non-ferrous metals for a minimum of 24 months without deterioration – and no need for regeneration. VpCI® powders are not consumed by the protective action. If the VpCI® layer is disturbed, it replenishes itself automatically with continuous vapor deposition.

When used for short- or long-term storage, the VpCI® layer need not be removed prior to start-up of equipment. However, removal – if necessary – is just as easy as application. Any low pressure air gun or simple water rinse will work.

Cortec® VpCI®s are environmentally safe. They do not contain nitrites, silicones, phosphates, heavy metals or other harmful chemicals.

VpCI® powders can be sprayed or blown into cavities or interiors having complex spaces. Certain VpCI® powders are water soluble for wet applications such as hydro testing. For pumps, heat exchangers, generators and piping, a VpCI® powder solution may be circulated through the system to assure contact with all surfaces. Drying is not necessary.

Powder may also be sprinkled or dispersed into small spaces, but should be fogged with a blower for spaces greater than 36 cubic feet (one cubic meter).
