ZERUST® Axxatec™ DA-23C

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-23C is hard water-tolerant and does not affect the cleaning performance. However, a decrease in corrosion protection is expected if hard water is used.

Tanks made out of mild steel, stainless steel, and poly-lined tanks are approved for use with Axxatec™ DA-23C. 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-23C. However, compatibility tests should be performed before combining Axxatec™ DA-23C with any non-ZERUST® wash solution.

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

• Applying Axxatec™ DA-23C on clean surfaces.
• Diluting Axxatec™ DA-23C 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-23C solution for greater than 1 minute (immersion or spray) before removal and drying.
• All metal surfaces are properly coated with Axxatec™ DA-23C.
• The coated surfaces are dried completely prior to handling or packaging.

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-23C. 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-23C with any non-ZERUST® VCI packaging.

No data has been collected on the impact Axxatec™ DA-23C has on paint adhesion. Therefore, it’s recommended to test paint adhesion on trial parts before painting any parts in production.

When Axxatec™ DA-23C 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-23C does not stain the metal surface. Axxatec™ DA-23C 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.

Yes, Axxatec™ DA-23C 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-23C with any non-ZERUST® rust preventative oil.

We were able to successfully stick weld steel sections that were applied with Axxatec™ DA-23C. However, some brown/ black carbonization residue was noticed and was not easily removed from the surface. Good welding practices are to scrub, sand, or wire brush the areas to be welded, which would remove Axxatec™ DA-23C from the area.

Axxatec™ DA-23C leaves trace residue on the metal surface at temperatures up to 752°F (400°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.

Axxatec™ DA-23C coating can be removed using ZERUST® AxxaWash™ cleaners (AxxaWash™ NW-10C, KF-121, KF-124) or any commercial alkaline cleaners.

To properly dry the coated parts, we recommend using a mechanical fan, air knife, and/or industrial heating oven (no higher than 302°F (150°C) and no longer than 30 minutes) after the parts are coated.

For optimum protection and best practice, it’s highly recommended to completely dry the Axxatec™ DA-23C coated parts before placing the parts inside any packaging or container. Axxatec™ DA-23C 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-23C 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 benefit is seen due to spray impingement on the metal surfaces. (Note: immersion application is not recommended when Axxatec™ DA-23C is used as a cleaner, as DA-23C’s superb 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-23C is designed to provide up to 3 months^‡ of indoor storage protection depending on the concentration % used (3 – 20%) and warehouse conditions (Temperature, RH).

Yes, Axxatec™ DA-23C 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-23C won’t revert any existing corrosion.

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).
