HDL 2524

> A Two-Part Liquid Alkaline Permanganate Product Scale Oxidizer, Hot Section, Jet Engine Parts

HDL 2524 is used as part of a multi-stage process to assist in the removal of oxides and complex metallic heat scales from jet engine components.

HDL 2524 is a two-part product.
HDL 2524C consists of liquid caustic alkali.
HDL 2524P consists of a concentrated liquid permanganate.

  • Liquid version easy to handle.
  • Highly effective oxidizer of complex heat scales without corrosion to base metals (ferrous and high temperature alloys).
  • Approved for use on high strength or high heat resistant alloys.
  • Minimum sludge formation at the bottom of the tank.

Add 20% (by volume) of water directly in the tank.  Add 30-50% (by volume) of HDL 2524C, and 15-25% (by volume) of HDL-2524P.  Fill the tank with water to working level, then stir the solution to mix.  Finally, heat solution to 82-93°C (180-200°F).

A heated tank constructed of 316 Stainless Steel is recommended.
Use of Agitating Equipment will generally enhance process results.
