EXTENDING MCI LINE
This product is a multifunctional admixture to concrete,
combining Cortec's exclusive Migrating Corrosion Inhibitor™
for rebar protection and superplasticizers for concrete flowability.
MCI-2007 CorrCrete™ is the first of its kind on the market
for concrete additives. It is recommended for use in all
concrete, especially reinforced, including prestressed and post-tensioned.
This water-based, water-reducing additive reduces the amount of
mixing water up to 20%. MCI-2007 CorrCrete™ provides
superior corrosion protection to reinforced steel, carbon steel,
galvanized steel and other metals embedded in concrete by forming
a protective layer on metal. Chloride concentration in the
concrete does not matter; MCI-2007 CorrCrete™ prevents corrosion
on the rebar. In addition, MCI-2007 CorrCrete™ is
environmentally friendly and does not contain any VOCs.
V/O and MCI-2022 V/O
Applications of MCI-2020 and MCI-2022 are often
done on vertical surfaces or on bridges in windy conditions.
Both of these situations can cause loss of the product due to
flowdown (vertical), misting (bridges), or excessive labor due
to the need for multiple coats.
avoid these problems, new more viscous versions of MCI-2020 and
MCI-2022 were developed and named MCI-2020 V/O and MCI-2022 V/O,
Both of these products adhere very well to concrete
surfaces and have relatively short drying times. They have
good sprayability, and can be applied with brush or roller as
well. In addition, MCI-2020 V/O and MCI-2022 V/O build a
thicker layer of product on the concrete surface, which allows
one-coat application instead of two.
ElectriCorr® VCI-286: Coating
are very proud to announce that Cortec has a coating that will
help our customers in the electronics industry.
VCI-286 is an acrylic-based conformal coating containing Cortec's
unique corrosion inhibitors.
This coating conforms well to metal surfaces, is
non-conductive and dries very fast. ElectriCorr®
VCI-286 has many advantages in comparison with conventional conformal
coatings. The most important are: Cortec's product contains
a corrosion inhibitor for multimetal protection, has exceptional
moisture resistance, and is VOC-free. (The solvent used
in this product was added to the list of compounds excluded from
the definition of VOC in June 2000.)
ElectriCorr® VCI-286 contains a special
UV light additive to help identify its presence on metal surfaces
by using UV light. Depending on the application, ElectriCorr®
VCI-286 is available in aerosol cans or in bulk liquid.
VCI-367: Solvent-based Temporary Coating
is the latest in a series of solvent-based temporary coatings
that provide excellent multimetal corrosion protection (1,000
hr. salt spray or humidity resistance at 2-mils). VCI-367
has several unique characteristics that sets it apart from all
other temporary coatings. It is non-tacky, does not run
when heated to 200+ºF (93ºC), can be immersed in water
and can even be topcoated in some cases.
There are several situations where VCI-367 would be used instead of a tacky
1. If the coating were subjected to constant heat, such as an air
conditioner in a warm climate such as Hawaii, VCI-367 would remain
in place and provide excellent corrosion protection. A tacky
coating would tend to run.
2. Some tacky temporary coatings brushed on screws thin out when
a second coating is applied. VCI-367 will build up film
thickness between coats, providing total protection of the screws.
3. A yellow alkyd was applied over VCI-367 to provide significantly
improved corrosion protection, compared to a straight alkyd.
The aesthetic appearance of the alkyd coating was better than
the brownish color of all temporary coatings.
This unique non-tacky epoxy-ester resin coating
was evaluated by one of our customers with great success.
The new coating contains very effective corrosion inhibitors and
provides extremely good protection at very thin film thicknesses.
For example, 0.03 to 0.09 mils thick films provide up to 20 hours
of protection in a salt spray environment. Films 1.4 mils
thick protect cold-rolled steel in salt spray environments for
more than 400 hours.
VCI-390 is waterborne and can be diluted with water
for dip applications. The product air-dries in 1 to 2 hours
and cures completely in one week at room temperature, forming
a nice transparent film on the metal surface. For customers
who are looking for a black coating, a black version of VCI-390
VCI Antistatic Stretch Film
Antistatic materials are of special
importance in packaging. Poor electrical conductivity of
plastics causes a lot of problems during production, handling
and use. The insulative property of plastic materials means that
friction or separating two plastic sheets may lead to the creation
of a charge. Dust and dirt may settle between the stretch
film layers. This may lower cling properties.
new Cor-Pak® VCI Antistatic Stretch Film meets
the requirements for antistatic film under MIL-B-81705C, Type
II, and has a surface resistivity of 109-1011
ohms/sq and a static decay of <2 seconds.
biggest advantage of Cor-Pak® VCI Antistat Stretch
Film is the combination of antistatic and VCI properties, providing
long-lasting multimetal protection.
This new product was developed specially for packaging
of sensitive electronics parts, such as circuit boards, motherboards,
etc. Cor-Pak® VCI Foam combines:
• Protection from corrosion damage
• Protection from physical damage (cushioning)
• ESD protection
Construction of the VCI foam is quite simple: Cortec's
VCI-126 or VCI-125 film is laminated to closed-cell polyethylene
foam (1/18" or 1/16" thickness). No adhesive is
needed for lamination.
Additional benefits include:
• Durability and reusability
• Water resistivity
• Resistance to most solvents and chemicals
Military Packaging – MilCorr™
A recent military document provides a more detailed definition of packaging:
"The processes and procedures used to protect
material from deterioration and damage. It includes cleaning,
drying, preserving, packaging, marking and unitization."
Now, a quick quiz:
To preserve, let's say a military vehicle, what
properties of the packaging material are desired?
Let's name the most important: ultra strength, corrosion protection, UV
protection, flame retardancy, superior shrink characteristics,
. . .
How many products do we need to meet all there requirements?
The answers are numerous if you don't ask Cortec
Corporation to help address your problem. We can solve this
task with just one product - MilCorr™ Shrink Film.
This composite film has everything you need - ultimate strength characteristics,
powerful multimetal VCI, ultraviolet and flame retardant package.
MilCorr™ was specifically designed to meet
the most stringent military requirements. Of course, you
can use it for "civil" applications, such as mothball
preservation of industrial equipment, export packaging, heavy
equipment, recreational vehicles (boats, snowmobiles), etc.
This new tan film is available in sheeting and tubing with a thickness
from 10 to 12 mils (250-300 microns).
Cor-Pak® Cocooning Stretch Film
A new low cost procedure to wrap metal coils in
a rolling position with bore/eye horizontal is now operational.
The process utilizes a semi-automatic stretch wrapper and Cortec's
unique Cor-Pak® Cocooning Stretch Film, specifically
designed for applications requiring a strong yet soft film.
It is now possible to cocoon-wrap coils fast and efficiently with
packaging that conforms to the metal product.
To properly protect eye horizontal coils against
corrosion and handling damage, several packaging components are
required. An ID insert to protect the bore/eye, an ID edge
protector to prevent handling damage when lifting, sidewall protection
to avoid damage from C-hook or equivalent when moving coils, and
an OD protector to prevent edge cuts during wrapping and stacking
of coils. However, the manual placement of these necessary
components negated goals for reduced labor and investment costs.
Cortec developed corrosion protection with each
of these required components. VCI-350 A and B are used for
fiberboard and corrugated, VCI-357 saturation coating for laminated
edge protection, VCI-126 films for ID tubes and edge wraps, EcoWeave®
where strength is required, and even VCI plastic corrugated for
converting as warranted.
Cocoon Wrap Method
Most manufacturers of stretch wrap equipment offer
various size and speed units in their semi-automatic line to cocoon
wrap coils. They can either furnish blocker rollers used
to roll the coil during wrapping or install over an existing blocker
roll system. These wrappers are available with an articulating
wrapper arm to move in and out for coil placement and removal.
Cost for the wrapper only with 12-18 rpm would be approximately
$20,000 US and compatible blocker rolls would be about $15,000
US installed, depending upon desired accessories. These
relatively low costs for mill equipment are what make this packaging
method universally available.
Cortec's high-performance Cor-Pak®
Cocooning Stretch Film is designed for maximum strength and holding
force with superior corrosion protection. For the Cocoon
Wrap method, trials found that other characteristics were required
leading to the developed of the unique Cor-Pak®
Cocooning Stretch Film. This innovative film maintains the
same advantages as regular Cortec stretch film. It also
conforms exceptionally well to the curvature of the coil and adheres
to prevent slippage and zippering of the film.
You know that Cortec's policy is to make environmentally
friendly products. Most of Cortec's products are very environmentally
friendly, but on the other hand they are also great fighters -
they are fighting corrosion on the metals. They fight corrosion
everywhere: in the air, water and oil, and they are winners!
Cortec's laboratory developed a new "green" line of "corrosion
fighters" based on soybean oil methyl ester instead of mineral
oil to make our products even more safe for our customers and
Four new products were developed based on soybean
oil methyl ester. All of these products were developed for
different applications, but have a lot in common: good lubricity,
penetrating properties, excellent corrosion protection, biodegradability
and environmental friendliness.
EcoLine™ Long-term Rust Preventative
This rust preventative is an excellent replacement
for oil- and solvent-based rust preventive materials. Containing
very effective corrosion inhibitors based on VCI technology, this
product provides dependable anti-corrosion protection in high
humidity atmospheres and chloride-containing environments.
This product is ready-to-use and can be applied
by dipping, spraying or brushing at many stages of metal fabrication,
storage or shipment. Protecting different kinds of metals,
EcoLine™ Rust Preventative provides protection when in contact
with the metal and from some distance as well, due to Cortec's
EcoLine™ All Purpose Lubricant
This product was designed for industrial, shop and
home use. In addition to the lubricity, which comes from
the soybean oil methyl ester, this product contains a friction
modifier and extreme pressure additive. Like all products
based on Cortec's technology, EcoLine™ All Purpose Lubricant
contains unique vapor corrosion inhibitors, which prevent corrosion
on uncoated and difficult to reach areas in cutting and stamping.
It also provides multimetal protection.
In addition to the above-mentioned properties, soybean
oil methyl ester has excellent cleaning/degreasing properties
and great solvency. These properties can be compared to
the same for D-Limonene and solvents like mineral spirits.
However, D-Limonene is flammable while mineral spirits are combustible
and not biodegradable. In addition, both solvents are 100%
VOC, while soybean oil methyl ester is VOC-free.
EcoLine™ Cleaner/Degreaser is a heavy-duty, water-dilutable cleaner/degreaser
for tough cleaning jobs in industrial and commercial applications.
It is ideal for cleaning machinery, shop tools, hoods, parts in-process,
food processing equipment, office equipment, floors, walls and
desks. The cleaner can be easily rinsed off the surface
with water and does not affect adhesion of paints or coatings.
This cleaner/degreaser also provides multimetal corrosion protection.
EcoLine™ Cutting Fluid
Cutting Fluid is a multifunctional biodegradable concentrate for
metal cutting operations. When added to water at a ratio
of 1:40 or 1:30, it gives a stable emulsion that provides excellent
cooling and little or no smoke during use. Being environmentally
friendly and biodegradable, this product is an effective lubricant
and very good anti-corrosion product for in-plant processing and
storage up to 4 months.
NEW ADDITIVES FOR AUTOMOTIVE INDUSTRY
M-529: Additive to Engine Oil
A new very economical additive to diesel and gasoline engine oils was developed
in Cortec's laboratory.
is well known that engines contain, along with ferrous metals,
a number of colored metals and their alloys. All of these
metals are very sensitive to high temperatures (oxidation) and
chemical/electrochemical corrosion. This corrosion may be
initiated by regular oil additives or "sour condensates",
and water-based low pH electrolytes, which are usually present
in engine and exhaust systems of cars.
M-529, when added to engine oil, provides excellent protection from all types
of corrosion: high-temperature, chemical and electrochemical,
in storage or "stop and go" conditions.
are a variety of different standard tests to pass when considering
an additive for engine oil. M-529 passed all these tests
and showed excellent results in real life conditions - it was
tested as an oil additive to a car engine. When added to
engine oil at 1.5-2% by weight, M-529 will solve all corrosion
VCI CorrVerter™ Stops Rust!
home, boat, auto - anywhere you have rust, our new VCI CorrVerter™
will help you. This water-based primer is recommended for
application to rusty or poorly prepared steel surfaces where further
corrosion protection is required. VCI CorrVerter™
is formulated to penetrate and eliminate rust, get down to the
bare metal and stop further rusting.
VCI CorrVerter™ contains a novel chemical
chelating agent that modifies the surface rust into a hydrophobic
passive layer. VCI CorrVerter™ combines this chelating
