Nox-Rust EV9

Nox-Rust EV9 is an environmentally safe and highly effective corrosion prevention liquid

If you could choose a corrosion preventive coating that works without polluting the ground or water, you'll choose Nox-Rust EV9, an environmentally safe liquid that is engineered to be effective and ecologically responsible.

EV9 is a vegetable (soybean) based, biodegradable protective coating. It is made with edible, food grade soybean oil which has been bleached and deodorized. It is very resistant to spoiling and going rancid over time. EV9 also contains proven Daubert corrosion inhibitors.

It is water-displacing, and has the viscosity to reach voids and recesses of intricately machined metal parts.

Low-VOC, non-toxic, non-flammable, and completely biodegradable.

It can be removed, if required, with high pressure steam or a hot alkaline wash. And because it is formulated with organic materials, it can be disposed of down the drain.

If you store or ship pipes, tubes, engineered parts, fabricated metals, transport equipment or similar, EV9 is the right coating for physical corrosion protection.

Metalworking additives

Nox-Rust 5400
Nox-Rust 5400 is a multi-metal inhibitor for general industrial use. Used as a wash, it leaves behind a lubricant and corrosion preventive film. It will not interfere with assembly sealers, adhesives, painting, welding, and cleaning solutions. Easy to remove by conventional cleaning methods. Approved for use in automotive manufacturing -- cold rolled steel, sheet metal stamping, automotive parts. Sold in pails, drums, and aerosol cans.

Nox-Rust 7100
Does your company manufacture springs, machine tools, compressors, gears, drive shafts, precision parts, watch components, taps, drills, and parts for refrigeration, aviation or transportation? Any plant operation with a stamping operation using water-base cutting fluids likely needs Nox-Rust 7100.

It is a light, water-displacing, transparent oil that repels residual cutting fluids. It will not clog stamping dies, a crucial benefit. It is also non-staining, another important quality for in-plant or cross plant processing.

The light oil dries to a soft dry film which is barely noticeable, except for the sparkling luster it puts on treated metal. Parts remain protected for 3-6 months indoors. Apply by dip, spray or brush. In most cases, removal is not necessary.

Nox-Rust 7800
Experienced users of Nox-Rust 7800 call it the best all-purpose lubricant they have ever tried! Shop mechanics, for example, use it for temporary corrosion protection, un-seizing a stubborn nut to keeping machines running smoothly.

Nox-Rust 7800 is a water displacing, low viscosity lubricant and corrosion preventive liquid. It will protect both ferrous and non-ferrous parts during storage and covered transit at low film thickness. No mixing or preparation is required.

It has the unique capability to creep and penetrate into very tight and hard-to-reach spaces. It remains fluid at -70°F, which is why the military uses it a gun oil for firearms in cold climates.

Nox-Rust 7800 is also ideal in transit and transportation industries, machined parts and even routine maintenance shop use. Apply it by spray, dip or brush. Corrosion protection is effective up to 12 months. If removal is required, use mineral spirits, hot alkaline wash or high pressure steam.
