Chem-Crest 77-C is a rust inhibitor concentrate designed for use as a rinse injection into an overflowing ultrasonic rinse tank, although it may be used as a standard final dip in certain applications. This product will provide long-term oxidation protection if used as directed of mild and tool-grade steels, as well as high-carbon stainless steels.

Chem-Crest 77-C is effective at the prevention of oxidation due to wash chemicals in use in the cleaning process, exposure to water, and hot-air drying as well as during storage while waiting for further processing or for final product.

Chem-Crest 77-C is typically used at 1–2% by volume in ultrasonic rinsing applications as an injection into the rinse stages. Normal operating temperatures: 100°–150°F, dependent on the material makeup of the substrate material. Contact your Crest representative for product-line-specific recommendations.
