Corrosion Prevention for Packaging
CORTEC’s unique VpCI (Vapour phase Corrosion Inhibiter) technology has extensive use in all forms of packaging, from the simple bagging of a component, to the packaging of a complete system.
Available in bulk form VpCI materials are particularly useful in packaging all forms of materials. The sheet and bubble-wrap can be used along with the emitters to give storage solutions of up to five years. Ruggedised materials such as CorShield, and EcoShield give excellent outdoor protection. For the ultimate protection MilCorr allows high cost military systems to be stored for up to five years.
For local protection and protection in transit for valuable items VpCI 126 Zip-Lock bags are available in a range of sizes, including 76x127mm, 152x203mm, 254x305mm and 305x457mm. Additional protection by the use of Cor-Pak 1-Mul sachets protect up to 1 cubic foot of space.
All these products offer protection of both
Ferrous and not ferrous metals. They do not contain nitrites, chromates or heavy metals.
Corrosion Recovery Equipment
Structural Tubing prior to rust removal
Protection of spare parts
When it comes to recovering equipment or tooling that has been corroded through poor storage, misuse or poor maintenance, HITEK can provide several products to help get the unit back into operation condition. Some of these products are the same as those in the Metals section, however. There are a few additional products such as the lubricants and temporary coatings that may prove useful.
Consider as an example a corroded piece of tooling that has been pulled out of store for use only to discover that it is tarnished and that some of the parts are seized. To recover this tool we would use the following procedure:
1.Clean the parts with one of the CORTEC cleaner/degreaser products
2.Remove the paint using the VpCI paint remover products
3.Clean using the cleaner degreaser
4.Remove the rust using the rust remover gel or liquid or wet grit blasting
5.Clean using the cleaner degreaser product
6.Apply lubricant/protective coating to moving parts
The equipment is now ready for use after use wipe down with CorrWipe 500 and place in VpCI 126 bag for corrosion free storage until next required.
VCI 422 - VpCI enhanced skin safe water based rust removers. The mild but effective rust removers come with the added benefit of the CORTEC vapour phase corrosion inhibitor technology. It is also effective at removing the tarnish from other metals such as copper, brass, chrome and aluminium.
VCI 423 - Gel version of VCI 422
VCI 416 - An extremely effective alkaline cleaner/degreaser that is water diluteable and normally used for temporary corrosion protection and cleaning for metal parts. When diluted with 4 parts water to 1 part VCI 416 the corrosion protect lasts for up to 6 weeks indoors on bare metal parts.
VCI 415 - Aircraft approved cleaner/degreaser to Mil-PRF-87937C, and several ASTM D specs similar to VCI 416.
CorrVerter - A water based rust converter for poorly prepared metal surfaces. Makes an extremely good primer for metals.
Corrwipe 500 - Removes light rust and tarnish from tools and parts leaving a very thin film of protective VpCI on the surface providing temporary protection for up to 6 weeks. The wipe and film has antistatic properties and therefore can be used to clean electronic circuits and components. The patented CORTEC corrosion Inhibitors are effective on most metals. The wipe is skin safe.
VpCI 609 - A water-soluble ferrous metal protection powder that can be used as an additive in wet blasting applications giving immediate protection to the blasted surface. Protecting it temporarily prior to further treatment or painting.
VCI 432/433 - Liquid paint remover with added VpCI technology from CORTEC. VCI 433 is the gel version of 432.
VCI 325 - Vegetable oil based lubricant and oil additive with VpCI technology.
VCI 368 - Oil based wax coating for long term protection of metal.
VCI 389 - Water based wax coating for long term protection of metal, water dilutable.
VpCI 126 - Vapour phase corrosion inhibiting film for storage and protection.

Corrosion Prevention for Long Term Storage
VpCI solutions for corrosion protection are commonly considered to be temporary solutions, offering short-term protection (up to 2 years). It simple solutions such as a resealable bag this is true and often more than adequate. However some situations, such as mothballing power stations, large pieces of machinery, military vehicles for long periods of time, say up to 10years require more innovative and radical approaches.
CORTEC combines its VpCI technology with barrier laminates, coatings and concentrates to extend the life of its storage solutions to the point where periods in excess of 10 years corrosion free storage are possible. Achieving this prolonged period of corrosion free storage requires special attention to preparation and cleaning prior to storage.
A few of the products that can be used in such situations are listed below. If you would like more information please contact HITEK
