CorrosionX 90101 Corrosion Inhibitor & Lubricant Aerosol 177ml

CorrosionX is a corrosion inhibitor, moisture displacer and lubricant. This is the standard thin-film formulation: a petroleum-based fluid that the manufacturer says uses polar bonding technology to form a fluid thin film coating on metal.

The manufacturer says it displaces moisture and the electrolytes that accelerate corrosion, penetrates through existing rust and corrosion, and leaves a thin, self-healing film. It also says it will not short sensitive circuits or interfere with electrical connections, and lists marine, industrial, household, automotive and sporting uses.

Where this product is used

• Marine hardware: winches, furling systems, windlasses, cleats, hatches, stanchions, downriggers, throttle cables and steering mechanisms
• Battery terminals, wiring harnesses, circuit breakers, fuse holders and electrical connections
• Industrial equipment: bearings and bushings, pulleys, air tools and power tools, stuck valves, wire rope and cable
• Electric motors, pumps, alternators and starters
• Locks, hinges, and door and window slides
• Automotive frames, lugs, nuts and bolts

Features

• Thin film of about 0.0004 in; the manufacturer's electronics-safe version of CorrosionX
• Displaces moisture and the electrolytes that accelerate corrosion
• Penetrates through existing rust and corrosion and leaves a self-healing film
• Lubricates: 0.249 mm four-ball wear scar and 0.083 friction coefficient on the manufacturer's data sheet
• 1,320 hrs in the ASTM D1748 humidity cabinet

Selecting the right option

This page covers the 177 ml aerosol and the 3.78 L liquid. The same formulation is also sold as CorrosionX 90102 Corrosion Inhibitor, Moisture Displacer & Lubricant Aerosol 473ml and CorrosionX 91002 Corrosion Inhibitor, Moisture Displacer & Lubricant Trigger Spray 473ml.

For a thicker film see CorrosionX XD Corrosion Inhibitor & Lubricant (medium-build) or CorrosionX HD Corrosion Inhibitor, Moisture Displacer & Lubricant (Heavy Duty, the thickest of the three).

Using it

The manufacturer's data gives no application directions for CorrosionX.

The data sheet advises testing a small sample first on adhesives, sealants containing silicone, and plastics not named in its compatibility list.

The performance figures above (humidity cabinet, salt spray, anti-wear, friction) are the manufacturer's values for CorrosionX; the data does not say whether they were measured on the aerosol or the liquid. The same applies to film thickness and coverage.

Storage and handling

Bulk: store at room temperature (50 °F / 10 °C or above); shelf life is indefinite while the container remains capped. Aerosols: store at no more than 120 °F (49 °C); shelf life is 3 years. The aerosol SDS also says not to expose cans to temperatures above 50 °C and to keep them away from heat and sunlight.

Limits and safety

The aerosol is an extremely flammable aerosol (Flammable Aerosols Category 1, signal word DANGER) containing gas under pressure, harmful if inhaled and an eye irritant (Category 2B); do not pierce or burn the can, even after use, and keep away from heat, sparks and open flame (aerosol SDS 17/07/20). The 3.78 L liquid is classified as a skin sensitiser (Category 1A), an eye irritant (Category 2B) and an aspiration hazard (Category 1B), signal word DANGER: it may cause an allergic skin reaction and may be fatal if swallowed and it enters the airways (bulk SDS 22/06/17). The SDS says excess heating above 180 °C over long periods degrades the resin. Check compatibility: butyl rubber may swell slightly, some adhesives may soften, silicone sealants may swell, polishes and some wax coatings may soften, and fabrics will stain (removable with naphtha or mineral spirits). The MIL-PRF listings are US military specifications only and are not an Australian approval.

Frequently asked questions

What is the difference between CorrosionX, CorrosionX XD and CorrosionX Heavy Duty?

Standard CorrosionX is the thin-film version, about 0.0004 in. XD is a medium-build thickened film that sits between standard and Heavy Duty. Heavy Duty is the thickest, about 0.005 in.

Is CorrosionX safe to use around electrical connections?

The manufacturer describes standard CorrosionX as electronics safe: it will not short sensitive circuits or interfere with electrical connections. The manufacturer's documents give two different dielectric strength values, so none is quoted here.

Does CorrosionX meet a military specification?

The manufacturer's product page lists MIL-PRF-81309H Type II and Type IV (Class 1 and 2) and MIL-PRF-16173E Class II (Grades 2, 3, 5). These are US military specifications, not Australian approvals.

What is the viscosity of CorrosionX?

33.2 cSt at 40 °C and 7.0 cSt at 100 °C, per the manufacturer's data sheet and SDS.

How long can CorrosionX be stored?

Bulk containers have an indefinite shelf life while capped; aerosols have a 3-year shelf life. Keep bulk at 50 °F (10 °C) or above and aerosols at no more than 120 °F (49 °C).

Are the aerosol and the 3.78 L liquid the same hazard class?

No. The aerosol SDS classes it as a flammable aerosol, Category 1, with flash point 132 °C. The bulk liquid SDS classes it as a skin sensitiser, eye irritant and aspiration hazard, with flash point 143 °C.
