  • Use diluted down with DI Water at 77-110°F (immersion with or without ultrasonic cavitation)

  • SOLO|RI™ Aqueous Rust Inhibitor (concentrated liquid) is an additive used by metal processing and fabrication plants at 1-5 % concentration diluted with filtered / DI Water at 77-110°F in the rinse water tank. In addition, it is suitable for treating, cooling, and retorting water, boilers, and steam lines in and around food processing areas. At an operating temperature of 77 - 110°F.
  • FOR Protecting Aluminum, Titanium, Brass, Copper, and Copper Alloys, DO NOT exceed the operating temperature of 110 °F in the FINAL RINSE tank. It is HIGHLY RECOMMENDED these metals be rinsed off with distilled warm water containing SOLO|RI™ and filtered hot air to dry out the parts.
