IBIT® -Antirust agent-

IBIT® BH and ASAHI AR (anti-rust agents) prevent tarnish (rust) from occurring in rinsing operations after acid/alkaline pickling or after processing treatment of steel sheets.

Features of Product

  • IBIT® BH and ASAHI AR have outstanding color change prevention functions in water washing process after acid pickling/alkaline cleaning.
  • IBIT® BH and ASAHI AR have a great ability to prevent color change of high-tensile steel sheets which tarnish easily.
  • The performance is more than satisfactory even at a lower concentration.
  • There is no adverse effect toward phosphate coating.
  • We are preparing neutral pH type for safety handling or non-nitrogen type for an environmental point
