ZERUST® Axxatec™ DA-24C

Tanks made out of mild steel, stainless steel, and poly-lined tanks are approved for use with Axxatec™ DA-24C. DO NOT USE an aluminum tank.

ZERUST® has a full line of AxxaWash™ cleaner products that are compatible with or even work synergistically with Axxatec™ DA-24C. However, compatibility tests should be performed before combining Axxatec™ DA-24C 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™ DA-24C. 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™ DA-24C with any non-ZERUST® VCI packaging.

When Axxatec™ DA-24C 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™ DA-24C does not stain the metal surface. Axxatec™ DA-24C 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™ DA-24C has on paint adhesion. Therefore, it’s recommended that paint adhesion be tested on trial parts before painting any parts in production.

Axxatec™ DA-24C is intended to be left on the surface for rust protection. However, Axxatec™ DA-24C coating can be removed using ZERUST® AxxaWash™ cleaners (AxxaWash™ NW-10C, KF-121, KF-124) or any commercial alkaline cleaners.

For optimum protection and best practice, it’s highly recommended to completely dry the Axxatec™ DA-24C coated parts before placing the parts inside any packaging or container. Axxatec™ DA-24C 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).

The corrosion protection provided by both applications is identical. However, immersion application for Axxatec™ DA-24C is recommended when large quantities of small parts are processed or when parts have holes, slots, internal surfaces, etc., that spray applications cannot reach. Additionally, if applied by spraying, additional cleaning benefits are seen due to spray impingement on the metal surfaces. (Note: immersion application is not recommended when Axxatec™ DA-24C is used as a cleaner, as DA-24C’s oil-splitting performance leaves a layer of oil at the top of the tank, causing oil to be left on the surface of the part when removed from the immersion tank).

Axxatec™ DA-24C is designed to provide up to 3 months^‡ of indoor storage protection depending on the concentration % used (3 – 20%) 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™ DA-24C do not have any VOC.

If the Axxatec™ DA-24C 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.”

Yes, Axxatec™ DA-24C 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™ DA-24C won’t revert any existing corrosion.

Yes, Axxatec™ DA-24C still may be used. However, you should bring the product back to ambient temperature and mix well before use.

No, the Axxatec™ DA-24C product has expired and may not provide the intended corrosion protection performance.

It is always best practice to use DI or RO water, as the bath life is improved when used. If DI or RO water is unavailable, Axxatec™ DA-24C is hard water-tolerant and does not affect the cleaning performance. However, a decrease in corrosion protection is expected if hard water is used.

Yes, concentrations higher than 10% may be used. Optimum corrosion protection is achieved when:

• Applying Axxatec™ DA-24C on clean surfaces.
• Diluting Axxatec™ DA-24C within the higher end of concentration (10-20%).
• High-quality water (DI or RO) is used.
• Allowing the metal surface to be in contact with Axxatec™ DA-24C solution for greater than 1 minute (immersion or spray) before removal and drying.
• All metal surfaces are properly coated with Axxatec™ DA-24C.
• The coated surfaces are dried completely prior to handling or packaging.

Yes, Axxatec™ DA-24C 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™ DA-24C with any non-ZERUST® rust preventative oil.

Axxatec™ DA-24C 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.

Yes. However, the surface temperature should be lower than 266°F (130°C).

To properly dry the coated parts, we recommend using a mechanical fan, air knife, and/or industrial heating oven (no higher than 266°F (130°C) and no longer than 30 minutes) after the parts are coated.
