Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Uniform Fine Satin or Frosted Etch
- Low-Foam Low-Mist Alkaline Etching
- BAC 5786 Operating Conditions
Product Description
BONDERITE® C-AK MIL-ETCH AERO is a granular alkaline cleaner and etchant formulated to produce a fine satin or frosted etch on aluminum and its alloys. The working solution develops a low-foam blanket to minimize caustic mist while providing excellent sequestering action that helps prevent scale and sludge buildup on tanks and heating coils. It is designed for aluminum surface preparation prior to deoxidizing, anodizing, and other finishing operations. :contentReference[oaicite:0]{index=0}
