ZERUST® Axxatec™ 48C

Tanks made out of mild steel, stainless steel, and poly-lined tanks are approved for use with Axxatec™ 48C. DO NOT USE an aluminum tank.

For spray applications, use a hand spray bottle intended for viscous fluids or a mechanical sprayer. If you would like to use conveyor spray equipment, contact your ZERUST®/EXCOR® representative for further information.

No, Axxatec™ 48C is not compatible with hard water. Instead, for optimal performance and extended bath life, it is advisable to use deionized or reverse osmosis water for both bath preparation and rinsing, as this helps minimize corrosion risk. If these options are unavailable and tap water must be used, it should first be treated with 0.2 – 1.5% ZERUST®/EXCOR® AxxaVis™ HST-10 before diluting Axxatec™ 48C. Always verify the compatibility with various metals prior to application. For tailored dilution guidelines based on specific operational needs and conditions, please consult your ZERUST®/EXCOR® account representative.

ZERUST® offers a full line of cleaner products that are compatible with or even work synergistically with Axxatec™ 48C. Compatibility tests should be performed before combining Axxatec™ 48C with any non-ZERUST® wash solution.

ZERUST® offers a complete line of VCI packaging products (e.g., ZERUST® ICT®510-C, ICT®520-HS, ICT®420-35) that are compatible or work synergistically with Axxatec™ 48C. However, compatibility tests have not been completed with any non-ZERUST® VCI packaging products, so it’s recommended to perform compatibility tests before combining Axxatec™ 48C with any non-ZERUST® VCI packaging.

Yes. However, the surface temperature should be lower than 302°F (150°C).

When Axxatec™ 48C is used as prescribed and coated parts are stored indoors or as part of corrosion protection for export parts packaged in boxes, crates, ZERUST® VCI packaging, and/or UV-resistant packaging, Axxatec™ 48C does not stain the metal surface. Axxatec™ 48C may, however, stain the metal surface if incorrectly used – such as if the coated parts are left outdoors without proper UV packaging protection and/or under direct sunlight (UV light) exposure during storage.

No data has been collected on the impact Axxatec™ 48C has on paint adhesion. Therefore, it’s recommended to test paint adhesion on trial parts before painting any parts in production.

Axxatec™ 48C coating can be removed using ZERUST® AxxaWash™ cleaners (AxxaWash™ NW-10C, KF-121, KF-124) or contact your ZERUST®/EXCOR® account representative for more specific removal recommendations on your particular operation and conditions.

For optimum protection and best practice, it’s highly recommended to completely dry the Axxatec™ 48C coated parts before placing the parts inside any packaging or container. Axxatec™ 48C has been tested to be compatible with ZERUST® VCI packaging (e.g., ZERUST® ICT®510-C, ICT®520-HS) and plain plastic packaging. Test before using any other types of non-ZERUST® VCI packaging (See ZERUST® VCI packaging guidelines).

Both applications provide identical corrosion protection. However, immersion application for Axxatec™ 48C is recommended when large quantities of small parts are processed or when parts have holes, slots, internal surfaces, etc., that spray applications cannot reach. If applied by hand spraying, additional cleaning benefit is seen due to spray impingement on the metal surfaces.

Axxatec™ 48C is designed to provide up to 6 months^‡ of indoor storage protection depending on the concentration % used (3 – 10%) and warehouse conditions (Temperature, RH). For long-term protection, you may place or wrap the clean parts with the use of ZERUST® ICT®510-C VCI bags and/or films for long-term (years)^‡ corrosion protection, such as export shipment or inventory storage (See ZERUST® VCI packaging guidelines).

Yes, a circulating pump is required, and the flow rate is tank size-dependent. Typical tank turnover should be 0.25 – 1.0 times per minute (for example, a 100-gallon tank should have a pump system with a minimum flow rate of 25 – 100 gallons/minute).

A filtration system is always recommended, and the filter size is dependent on the customer’s cleanliness level requirement. A typical filter media size is ten microns (10 μm).

No, VOC is not present in the concentrate product, and therefore, parts coated with Axxatec™ 48C do not have any VOC.

Yes, welding quality is affected, so it is recommended to follow best welding practices, such as scrubbing, sanding, or wire brushing the areas to be welded, which would remove Axxatec™ 48C from the area.

If the Axxatec™ 48C coating is applied in excess, not properly diluted, or not properly drained or dried, it may result in a higher concentration (thicker) of the product on the surface of the part, leading to stickiness. Although this thicker coating offers stronger corrosion protection, the product will no longer be “dry-to-touch.”

Axxatec™ 48C coating burns off the metal surface at temperatures higher than 302°F (150°C), so we do not anticipate a negative impact on the heat treatment process. However, as always, it is best practice to test before use.

After coating the parts, we recommend using a mechanical fan, air knife, and/or industrial heating oven (no higher than 302°F (150°C) to dry them properly.

Yes, Axxatec™ 48C may be reapplied onto the parts. As always, it’s recommended that the parts are clean and free from debris, oil, or other contaminations before reapplying. NOTE: The reapplication of Axxatec™ 48C won’t revert any corrosion that already exists.

Axxatec™ 48C is not designed to provide outdoor protection. If outdoor protection is needed, AxxaCoat™ 90BHFS, Axxanol™ Spray-G, Axxanol™ Z-Maxx, or Z-Maxx LV is recommended.

Axxatec™ 48C coating remains stable with temperatures up to 302°F (150°C). However, temperatures above 302°F (150°C) will result in Axxatec™ 48C coating breaking down and no longer offering corrosion protection.

Yes, concentrations higher than 10% may be used. However, concentrations higher than 10% can leave a tacky residue on the surface upon drying and offer only small incremental gains in corrosion protection.
Optimum corrosion protection is achieved when:
• Applying Axxatec™ 48C on clean surfaces.
• Diluting Axxatec™ 48C within the higher end of concentration (6-10%).
• Allowing the metal surface to be in contact with Axxatec™ 48C solution for greater than 1 minute (immersion or spray) before removal and drying.
• Maintaining Axxatec™ 48C working solution within optimal operating temperature range: ≥72°F (22°C).
• All metal surfaces are properly coated with Axxatec™ 48C.
• The coated surfaces are dried completely prior to handling or packaging.

Yes, Axxatec™ 48C has been tested compatible with ZERUST® solvent and oil-based rust preventatives (e.g., Axxanol™ A35CD-32, 33CD, Spray-G). However, it is always recommended that a compatibility test be performed before combining Axxatec™ 48C with any non-ZERUST® rust preventative oil.

Parts coated with Axxatec™ 48C, as per instruction, do not negatively affect commonly used DEXRON-VI automotive transmission fluid (ATF) density, viscosity, or friction (slip speed). However, we always recommend testing before use. Contact your ZERUST® account representative for more information on ATF compatibility.

No, the Axxatec™ 48C product has expired and may not provide the intended corrosion protection performance.
