ZERUST® Axxanol™ 718-ESS

Axxanol™ 718-ESS was designed for protection applications where ZERUST® Vapor Capsules may not provide adequate protection, such as electrical panels, etc., containing air exchange. Since ZERUST® Vapor Capsules protect metals using Vapor Corrosion Inhibitors (VCIs), which slowly release into a sealed air space and form a strong bond with the metal surface, preventing corrosion on the metal surface. As a result, if your enclosure has any air exchange, the VCIs will leave your enclosure and not provide adequate protection, so Axxanol™ 718-ESS should be used to protect your metal assets in these situations.

Since Axxanol™ 718-ESS is a stand-alone corrosion inhibitor product that creates a coating on the metal surface, the VCIs may not reach the metal surface, so it will not provide any additional corrosion protection. However, if there are hard-to-reach metal surfaces that are not coated by Axxanol 718-ESS and are in a sealed enclosure, ZERUST® Vapor Capsules may be used to provide VCI protection to those surfaces.

Yes. However, Axxanol™ 718-ESS is a stand-alone corrosion inhibitor product. If your application requires additional VCI, ZERUST® offers a complete line of Vapor Capsules (e.g., VC1-1(s), VC1-1, VC2-1, VC2-2, VC6-1, VC6-2) that are compatible with Axxanol™ 718-ESS. However, compatibility tests have not been completed with any non-ZERUST® VCI emitter and diffuser products, so it’s recommended to perform compatibility tests before combining Axxanol™ 718-ESS with any non-ZERUST® VCI emitters or packaging products.

Yes, Axxanol™ 718-ESS contains ingredients that may settle over time. Therefore, for Axxanol™ 718-ESS to perform as designed, you must shake well to ensure that these ingredients mix well before use.

Yes, however, the Axxanol™ 718-ESS bottle must be shaken thoroughly before use. At temperatures 25°F (-4°C) and lower, the product will thicken and come out as a stream instead of a spray.

No, the Axxanol™ 718-ESS product has expired and may not provide the intended corrosion protection performance.

Yes, always ensure that the power is off before applying Axxanol™ 718-ESS. If possible, ventilate the area you are applying Axxanol™ 718-ESS to minimize smell and accelerate drying after application.

The Axxanol™ 718-ESS bottle should be positioned 4 – 6” from the clean, dry, and dust-free surface(s) that need protection when spraying a light mist over the surface(s). Allow 10 – 15 minutes for the coating to dry, and apply another light mist after to ensure adequate coverage.

Drying times vary with the thickness of the Axxanol™ 718-ESS applied, the environment temperature, and the surface profile of the coated area. We recommend waiting 15 minutes or longer after the application of Axxanol™ 718-ESS before turning the power back on. Axxanol™ 718-ESS will dry to a soft, oil sheen, non-harden layer. Ideally, parts should be air-dried to ensure an even coating. However, a low-volume fan may be used to shorten drying time. High pressure and heat should be avoided as this can create thin coating areas or cause the solution to sag from the surface while drying.

Corrosion protection periods for electrical components will vary depending on the exposure of the components to the environment. While it is very hard to determine the duration of protection due to multiple factors such as humidity, temperature, acid gas, cleanliness of the metal surfaces, etc., we recommend reapplying Axxanol™ 718-ESS every 6 to 12 months depending on your access to the components.

Yes, make sure that the surface is free of dirt and/or dust before reapplying. Follow the instructions on the product label for spraying Axxanol™ 718-ESS. NOTE: The reapplication of Axxanol™ 718-ESS won’t revert any corrosion that already exists.

While it is very hard to determine the duration of protection due to multiple factors such as humidity, temperature, acid gas, cleanliness of the metal surfaces, etc., Axxanol™ 718-ESS can protect up to months indoors and days/weeks outdoors.

Axxanol™ 718-ESS will dry to a soft, oil-sheen, non-hardening layer. Drying times vary with the thickness of the Axxanol™ 718-ESS applied, the environment temperature, and the surface profile of the coated area. Typically 15 minutes or longer after application of Axxanol™ 718-ESS would be sufficient, but if the coated surfaces have many recesses and pooling of Axxanol™ 718-ESS, a longer drying time will be required. Ideally, parts should be air-dried to ensure an even coating. However, a low-volume fan may be used to shorten drying time. High pressure and heat should be avoided as this can create thin coating areas or cause the solution to sag from the surface while drying.

No, Axxanol™ 718-ESS does not leave a coating that is conducive to paint adhesion. Therefore, surfaces should be thoroughly cleaned with solvent or alkaline cleaners before painting.

Axxanol™ 718-ESS protected steel in acid gas testing up to 130°F (54°C). However, performance was reduced at temperatures ranging between 130-212°F (54-100°C) with minimal protection above 212°F (100°C).

When Axxanol™ 718-ESS is used as prescribed, substrates tested show no staining, but testing specific metals before use is always recommended.

You may remove the Axxanol™ 718-ESS coating using mineral spirits or alkaline cleaners and gentle wiping with a lint-free cloth.
