CorrosionX 90104 Heavy Duty thick-film corrosion inhibitor

CorrosionX Heavy Duty is the thickened-film version of CorrosionX, a corrosion inhibitor, moisture displacer and lubricant. This is the 90104 aerosol. It slowly penetrates existing rust and corrosion, removes moisture and then seals the moisture out. Unlike wax coatings, the film will not dry out, stiffen or crack.

Key specifications

Using it

No directions for application, film build or re-application intervals. Heavy Duty pretty much stays where it is sprayed.

Slight swelling or softening of butyl rubber. Some adhesives may soften and silicone sealants may swell slightly, so test a small sample first. Paints typically used on aircraft, automobiles and machinery are unaffected; polishes and some wax coatings may soften. It is compatible with acrylic, polyester, nylon, vinyl, Delrin, PTFE, Formica, polyethylene and polypropylene. It is absorbed into the fibres of most fabrics and will stain them. The stain is not permanent and can be removed with naphtha or mineral spirits.

Use outdoors or in a well-ventilated area, avoid breathing mist and vapours, and do not spray on an open flame or other ignition source.

Storage and handling

Store aerosols at not more than 49 °C (120 °F), in a cool, dry, well-ventilated place in the original container, away from heat and sunlight. An aerosol shelf life of 3 years.

Choosing the right option

Heavy Duty is the thickest of the three CorrosionX films. The standard thin-film grade is CorrosionX 90102 Corrosion Inhibitor, Moisture Displacer & Lubricant Aerosol 473ml (aerosol), and CorrosionX XD Corrosion Inhibitor & Lubricant is the medium-build version between the two.

Use the standard thin-film grade for electrical and electronic gear.
