Dynaprep AS #2

Product Code

0038136

Product Description

DYNAPREP AS No.2 is a proprietary, nitric acid-free desmutter for aluminum and its alloys. It is ideal for removing smuts and oxides that form in alkaline etching solutions and the resulting aluminium surface is highly active for subsequent processing. DYNAPREP AS No.2 is a powdered product that is used with water and sulphuric acid to make a safe, highly stable solution for stripping zincate from aluminum. DYNAPREP AS No.2 can also be used to make a non-chelated, mild etch solution for copper. When used as recommended, this mixture will provide a clean, uniformly micro-etched copper surface that will readily accept electrolytic or electroless copper or nickel in printed circuit board or commercial applications. 

Performance Features

  • Safer to use, handle and store than liquid acids.
  • Non-foaming, non-fuming, non-chelated, non-nitric, non-ammonium, non-chloride,
  • non-fluoride formulation.
  • Improves adhesion of subsequent finishes.
  • Can be used for stripping zincate from aluminum when double zincating.
  • Can be used to provide a uniform micro-etched surface on copper to ensure consistent adhesion of metallic or organic finishes.
  • Very economical to use.
  • Does not attack aluminum surfaces.
  • Can be used in immersion or spray applications.
