Corrosion Prevention
VAPOUR PHASE CORROSION INHIBITER (VPCI) TECHNOLOGY
|
Cortec’s unique VpCI (Vapour phase Corrosion Inhibiter) technology has
extensive use in Electronics and Electrical applications.
From simple anti-static VpCI 125 bags for the safe storage of circuit
boards and assemblies which allow materials to be stored for two years
and more without oxidisation and corrosion, to the highly loaded
emitters such as the VpCI 111 which will condition 11 cubic feet of
electronic enclosure, Cortec
materials are the safe eco-friendly solution for protection.
Cortec VpCI Foam Pads are a very cost effective solution and can be
supplied pre-cut, or on a roll for easy cut to length applications.
EcoSpray 238 is ideal for spraying onto cables and connections and will
give excellent protection of all electronics in adverse conditions.

CORROSION INHIBITER 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 non ferrous
metals. They do not contain nitrites, chromates or heavy metals.

LONG TERM CORROSION PROTECTION SOLUTIONS
VpCI solutions for corrosion protection are commonly considered to be
temporary solutions, offering short-term protection ( up to two years ).
In 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 ten years 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.
Below are listed a few of the products that can be
used in such situations:

RUST AND TARNISH
REMOVERS FOR METALS
Hitek-nology offers a range of the Cortec products when it is necessary to
recover metal or equipment that has been poorly stored or just needs to
be refurbished. The products include environmentally friendly rust and
tarnish removers that are skin safe and paint removers that are
extremely mild in comparison to some other products on the market. There
are also maintenance wipes that can be used to protect tools and
instruments, as well as cleaning circuit boards.
The typical process in recovering a metal component or assembly is as
follows:
-
Clean off excess dirt and grease using one
of the Cortec cleaners and degreaser such as VCI 416. Typically this
is done with a pressure washer.
-
Remove any paint using one of the Cortec
paint removers such as VCI 433
-
Remove rust using blasting with added VCI
609 or the rust remover VCI 423
-
Clean again to stabilise the VCI 423 with
VCI 416 or VCI 415, not necessary if using wet grit blasting
-
Apply CorrVerter if necessary. The metal
is now ready for top coating

PROTECTION FOR YOUR
EQUIPMENT
When it comes to recovering equipment or tooling that has been corroded
through poor storage, misuse or poor maintenance, Hitek-nology 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:
-
Clean the parts with one of the Cortec cleaner/degreaser products
-
Remove the paint using the VpCI paint remover products
-
Clean using the cleaner degreaser
-
Remove the rust using the rust remover gel or liquid or wet grit
blasting
-
Clean using the cleaner degreaser product
-
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.

REPAIR AND REFURBISHMENT
For maintenance,
repair and refurbishment, Hitek can supply some of the most
environmentally friendly products on the market today. In addition
to the products that are also on the other recovery pages, this page
includes products for lubrication and final permanent coating. See
some of the products listed below:

Corrosion Protection
When it comes to protecting metal assets such as expensive parts, work
in progress, assemblies, tooling, jigs, fixtures, classic cars,
vehicles, aircraft engines, and spares, the Cortec solutions supplied by
Hitek are both comprehensive, safe, environmentally friendly and cost
effective.
From the simple and popular VCI 126 blue film (now also available in the
fully 100% biodegradable version) to the spray on wax coatings and
lubricants such as the VpCI 389D water based hard coat and the soya
based VpCI 325 general purpose lubricant Hitek can provide a total life
solution, from initial manufacture to shipping and storage and lifetime
use.
Protection of work in progress, especially having undergone expensive
later stage finishing operations can be achieved easily, either by using
one of the environmentally friendly cutting fluids or by simply washing
the part in the popular VCI 416 water-dilutable alkaline wash. This wash
protects parts from corrosion for up to six weeks. If additional
protection is desired that packing the parts in trays or crates lined
with the VCI 126 film will protect the parts for up to two years.
In the case of classic cars, motorcycles, vintage vehicles, and sporting
guns, Hitek can provide custom made covers such as the car cocoon and
gun bags, made from the Corshield™ or Ecoweave™ products.
