ZERUST® AxxaWash™ KMS-305AL

For optimum performance and best practice, it is always recommended to use deionized (DI) or reverse osmosis (RO) water. This will also ensure that the bath life is improved when used. However, if DI or RO water is unavailable, AxxaWash™ KMS-305AL is hard water-tolerant. We found no significant difference in cleaning between the bath made with tap water (200 – 250 ppm hardness) and DI water. Water with high levels of hardness can increase scale deposits throughout the system.

Immersion application is not a recommended process for AxxaWash™ KMS-305AL.

Yes, you may use concentrations higher than 5%. However, if concentrations of 10 – 15% are used, the product may not rinse as well, and an alternative AxxaWash™ product with greater cleaning power would be recommended.

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 AxxaWash™ KMS-305AL. However, compatibility tests have not been completed with any non-ZERUST® VCI packaging products, so it’s recommended that compatibility tests be performed before combining AxxaWash™ KMS-305AL with any non-ZERUST® VCI packaging.

It is recommended that AxxaWash™ KMS-305AL be thoroughly rinsed and dried from the surface before any painting processes.

Yes. However, the surface temperature should be lower than 122°F (50°C).

AxxaWash™ KMS-305AL has not been tested for heat treatment.

AxxaWash™ KMS-305AL was tested and remained stable with temperatures up to 140°F (60°C). If bath temperatures exceed 165°F (73.9°C), check with your ZERUST® representative for recommendations.

No, AxxaWash™ KMS-305AL will not stain aluminum or ferrous substrates when used as described. However, any un-rinsed parts or parts exposed to the vapor phase may exhibit some staining if not properly rinsed.

No, AxxaWash™ KMS-305AL is not compatible with solvent and oil-based rust preventatives.

To properly dry the coated parts, we recommend using a mechanical fan, air knife, and/or industrial heating oven at 212°F (100°C) or higher after the parts are coated.

No, parts should be thoroughly rinsed, dried, and as close to room temperature as possible before packaging. AxxaWash™ KMS-305AL 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® packaging guidelines).

AxxaWash™ KMS-305AL is easily removed by rinsing with purified water, such as reverse osmosis or deionized water. Using warm water during the rinsing process will remove AxxaWash™ KMS-305AL faster.

Dip/immersion applications are not recommended for AxxaWash™ KMS-305AL. AxxaWash™ KMS-305AL is designed as a spray cleaner, and cleaning effectiveness is decreased in immersion applications. In addition, the rapid oil-splitting performance of AxxaWash™ KMS-305AL will likely cause the redeposition of soils on parts when they are removed from the bath.

AxxaWash™ KMS-305AL is designed to be rinsed from the surface. Aluminum surfaces should be kept as dry as possible to prevent excessive oxidation and water spots. On ferrous substrates, AxxaWash™ KMS-305AL left on the surface offered some very short-term corrosion protection but is not recommended, and a dedicated rust inhibitor (Axxatec™ or Axxanol™ product) should be used to protect those substrates.

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 that has a minimum flow rate of 25 – 100 gallons/minute).
