Remove Rust and Corrosion Inexpensively. Effectively Easily and Safely While Adding Corrosion Protection
Our rust removers, metal conditioners and paint strippers are biodegradable and non-polluting when
compared to other industrial products—eliminating and/or reducing virtually all waste disposal problems.
Corrosion is a persistent problem that must be carefully handled in a step-by-step process. Cortec’s environmentally
friendly products make it easy to clean metal, remove rust, condition and prepare metal for temporary or permanent coatings
and packaging. Cortec Surface Preparation products also add VCI corrosion protection.
Step One - Remove Oil Greases and Soil
Cortec® VpCI®-411 & VpCI®-411 Gel Cleaner Concentrate
Cortec®’s VpCI®-411 concentrated cleaner is biodegradable, organic
and made from natural solvents.This heavy-duty, versatile cleaner
can be used in a variety of household, commercial and industrial
applications i.e., adhesives and greases.VpCI®-411 is effective on a
broad range of metal surfaces, especially those susceptible to
deterioration in an alkaline environment.This product not only
inhibits corrosion of freshly cleaned surfaces, it is safe to the
touch and has a fresh lemon scent.
Cortec®’s VpCI®-414 is a non-toxic, biodegradable, water soluble
cleaner concentrate.This heavy-duty temporary coating and wax
remover is extremely effective in the removal of dirt, oils and
greases or other cosmoline-like products.As a viscous liquid,
VpCI®-414 is ideal for under-hanging and vertical applications.
After rinsing with water,VpCI®-414 will provide multimetal
corrosion protection for 24 to 48 hours.
Cortec®’s VpCI®-415/416/417/418/419 products are heavy-duty
cleaners/degreasers which provide the first step needed in
preventing rust and corrosion. Unlike many industrial cleaners,
VpCI®-415/416/417/418/419 are non-toxic, non-corrosive,
non-flammable cleaners that also provide multimetal corrosion protection.
VpCI®-415 offers unique flash corrosion protection and is
formulated to meet the requirements for cleaning and corrosion
protection of aircraft. VpCI®-415 conforms to MIL-PRF-87937C.
VpCI®-416 is a liquid, water-based,
environmentally friendly and
nitrite-free product.The low
foaming VpCI®-417 and 418
powders are excellent for power
washing equipment and agitation
tanks.VpCI®-419 is a liquid chemical
concentrate that is ideal for low
foaming floor cleaning applications.
Cortec® Corwipe® 300 and 500 Multipurpose Wipes
Multipurpose wipe cleans
while applying a corrosion
inhibiting layer to
grease, oil and light
rust. A must for
any tool kit. This wipes a treated with a water based cleaner with temporary rust preventative additives. It is specially useful for smaller scale parts cleaning prior to the use of VCI rust preventative products.
Corwipe® 500 is designed to clean, protect and
maintain products, components or assemblies such as:
• Machined parts coated with waxes or greases prior
• Static sensitive equipment
• Manual and power tools
• Aircraft and satellite components and assemblies
• Communications equipment
• Computer data storage devices
• Computer monitors and keyboards, TV screens, CD
players, equalizers, stereo speakers, etc.
• PC boards, terminal blocks
• Power connections, audio connectors
• Military equipment, ammunitions and missile
Step Two - Remove Old Paint
Paint Strippers & Cleaners
Cortec®’s VpCI®-432/433 Paint Strippers and Cleaners are
environmentally safe for removing paint from metal, wood and
concrete, as well as providing protection against corrosion, flash
rusting and discoloring of stainless steel, iron, copper, aluminum
and brass.The heavy-duty formulation, which removes paint in
three to thirty minutes, also effectively removes graffiti from
concrete.These paint strippers, developed with maximum user
safety in mind, do not contain many of the chemicals — such as
methylene chloride, chlorinated solvents, methanol, toluene and
acetone — found in other competing products.
Cortec®’s VpCI®-432/433 Paint Strippers are formulated to
remove urethanes and difficult-to-remove epoxies.They can
handle the toughest coatings, yet are very safe compared to
heavy-duty paint strippers. Works for removing Epoxy Coatings as well!
Step Three - This Is How You Get Rust Off Metal
Cortec® VpCI®-422 Liquid &
VpCI-423® Gel Organic Rust
Removers & Cleaners
Cortec’s VpCI®-422 and VpCI®-423 are non-polluting rust
removal products which can be easily and safely applied
to most metals.These products are based on a new
chemical breakthrough to remove rust from metal and tarnish from steel, cast iron, copper, brass and chrome. Unlike other
products currently available, these formulations are
not based on hazardous acids, and when used correctly
will not harm human skin or adversely affect most paints,
plastics, wood, textiles, ceramics or rubber.
VpCI®-422 and VpCI®-423 are completely organic, 100% biodegradable and don't require special disposal for typical
use. It is especially helpful for outdoor and marine applications where chemical waste disposal can be a problem. In
rare situations, waste treatment may be required if a
sufficient quantity of pollutants are introduced into the
chemical solution. Both VpCI®-422 and VpCI®-423 are awarded with a USDA Certified Biobased Label.

Rust and Scale Remover
EcoClean® Rust and Scale Remover is a heavy duty biodegradable scale and rust remover. It is one of the fastest acting products on the market for dissolving heavy scale, corrosion, and naturally occurring oxides off metals. It is effective and safe rust removal on cast iron, carbon steel, stainless steel, copper, aluminum, magnesium, and their alloys. Powerful corrosion inhibitors contained in the scale remover protect treated metals from flash rust. EcoClean® Scale Remover is simple to use and non-toxic, providing one safe remover for all your descaling and de-rusting needs.
EcoClean® Scale Remover is awarded with a USDA Certified Biobased Label (USDA#5564). It is easily biodegradable.
For water-soluble pouch form, use one pouch for every 4 gallons of water. Simply throw the pouch in the water. It will dissolve upon entering water and release the scale remover inside. It is particularly convenient for rust removal and scale removal where water circulates, as in many heatexchanger or pipe systems. For powder form, add 7% (by weight) in water. For ready-to-use liquid form, add 1 part product to 2 parts water.
EcoClean® Rust and Scale Remover water soluble pouch is available in 2.2
lb bags, 4 bags per carton.
EcoClean® Rust and Scale Remover powder is available in 5 lb (2.3 kg), 50
lb (22.7 kg), and 100 lb (45.4 kg) bags.

CorrVerter® - Single component water based rust converter
When removing rust may proove to be inconvenient, CorrVerter® is a fast drying, water-based one coat system (primer) rust converter that converts rusted surfaces to a hydrophobic passive layer and prevents further rusting thru the unique formulation of chelating agents and PVC resins. It provides long term corrosion protection by itself or by topcoating for extended performance.
Application: Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface contamination that could affect adhesion. For production line applications, use VpCI®-440 or similar phosphatizing pre-treatment.

Complete Cortec® Surface Treatment process prior to Coating
Coating Adhesion Improver
VpCI®-440 is a water-based surface pretreatment for steel, iron, aluminum, brass, copper, zinc and other metals. VpCI®-440 can replace phosphatizing and chromating systems. VpCI®-440 will help coatings adhere better to hard to adhere to surfaces, such as increasing the adhesion of a powder coating to aluminum.
Dip the parts for 5 minutes in a tank of diluted VpCI®-440 and allow to dry. Once parts are dry to the touch, usually within 5-10 minutes, the parts can be handled and painted.
