ZERUST® Axxanol™ A35CD-32

No, parts coated with Axxanol™ A35CD-32 that are fully dried do not have any VOC. VOC is present in the ready-to-use Axxanol™ A35CD-32 product. However, when the coating fully dries on the part’s surface, the VOCs evaporate.

Tanks made out of 304 or 316 stainless steel are recommended. Mild steel tanks can be used but should have good structural integrity and be maintained in good working order. Plastic and poly-lined tanks should be avoided.

ZERUST® has a full line of cleaner products (e.g., AxxaWash™ KF-121, KF-123, KF-124, etc.) that are compatible or even work synergistically with Axxanol™ A35CD-32. Before combining Axxanol™ A35CD-32 with any non-ZERUST® wash solution, a compatibility test should be performed.

ZERUST® offers a complete line of VCI packaging products (e.g., ICT®420, ICT®510, ICT®520, etc.) that are compatible or work synergistically with Axxanol™ A35CD-32. However, ZERUST® has not completed any compatibility tests with any non-ZERUST® VCI packaging products, so it’s recommended that the end-user performs their own compatibility tests before combining Axxanol™ A35CD-32 with any non-ZERUST® VCI packaging.

No, there are components in Axxanol™ A35CD-32 that do not make it conducive to paint adhesion. Therefore, it’s recommended that the Axxanol™ A35CD-32 coating is removed with ZERUST® AxxaWash™ products (e.g., AxxaWash™ KF-121, KF-123, KF-124, etc.) or commercial alkaline cleaners prior to painting.

Axxanol™ A35CD-32 coated 1/8” cold rolled steel plates were successfully stick welded together. 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 Axxanol™ A35CD-32 from the area.

Yes. However, the surface temperature should be lower than 110°F (43°C).

At a temperature of 635°F (335°C), 99% of Axxanol™ A35CD-32 was burned off. Therefore, we do not anticipate any negative impact on the heat treatment process under ideal conditions. However, for best practice, we recommend testing before use or washing off Axxanol™ A35CD-32 with a ZERUST® wash solution (e.g., AxxaWash™ KF-121, KF-123, KF-124, etc.) before heat treatment.

If the Axxanol™ A35CD-32 coating is applied in excess or is 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 “near dry-to-touch” and will have VOC.

No, when Axxanol™ A35CD-32 is used as prescribed and coated parts are stored indoors or as part of corrosion protection for export parts packaged in boxes, crates, VCI packaging, and/or UV-resistant packaging, Axxanol™ A35CD-32 does not stain the metal surface.

The Axxanol™ A35CD-32 coating may be removed using ZERUST® AxxaWash™ cleaners (e.g., AxxaWash™ KF-121, KF- 123, KF-124, etc.) or any commercial alkaline cleaners.

For optimum protection and best practice, it’s highly recommended to completely dry the Axxanol™ A35CD-32 coated parts before placing the parts inside any packaging or container. Axxanol™ A35CD-32 has been tested to be compatible with ZERUST® VCI packaging and plain plastic packaging. Test before using any other types of non-ZERUST® VCI packaging (See ZERUST® packaging guidelines).

Axxanol™ A35CD-32 contains a high-flash solvent. Therefore, drying/solvent evaporation times are highly dependent on temperature and humidity. Axxanol™ A35CD-32 typically dries in roughly one hour at 70°F (21°C). You may accelerate drying by placing parts in an oven at no more than 140°F (60°C) for 10 – 15 minutes or under a mechanical fan or air knife for ~ 30 minutes. If a fan or air knife is used, clean filtered air should be utilized to prevent debris and/or contaminations from attaching to the surface.

The corrosion protection provided by both applications is identical. However, immersion application for Axxanol™ A35CD-32 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 spray, additional cleaning benefit is seen due to spray impingement. However, you should ensure proper draining of the excess product and completely dry the coating to avoid any sticky residue on the part’s surface.

Axxanol™ A35CD-32 is designed to provide up to 1 year^‡ of indoor storage protection, depending on warehouse conditions (Temperature, RH), without additional packaging. For long-term protection, you may place or wrap the clean and dry 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 rates should be 3x -5x per hour. For example, a 100-gallon tank should have a pump sized with a minimum flow rate of 300 – 500 gph (gallons per hour) or 5 – 8.33 gpm (gallons per minute).

A filtration system is always recommended, and the filter porosity is dependent on the customer’s cleanliness level requirement. A typical filter media size is 25 to 50 microns. However, it is recommended to use a 5-micron stainless steel reusable filter, such as those available from www.homebrewit.com.

There are several efficient ways to reduce evaporative losses in a tank, including; Minimizing the entry opening by using a narrower dip cage, adding walls around the dip tank opening, using floating polypropylene balls to reduce liquid surface exposure, and avoiding a direct suction fan over the immersion tank, etc.

The most effective way to reduce evaporative losses in a spray sump system is to ensure that the sump tank is covered at all times. You may also use floating polypropylene balls to reduce liquid surface exposure, which will help reduce evaporative losses. Also, keep in mind that Axxanol™ A35CD-32 should not be recirculated or reused due to evaporation and contamination concerns.

Yes, Axxanol™ A35CD-32 may be reapplied to the parts. As always, it’s recommended that the parts be clean and free from debris, oil, or other contaminations before reapplying. NOTE: The reapplication of Axxanol™ A35CD-32 won’t reverse any corrosion that already exists.
