Sifco DPS6123 (1-Ltr-Btl)

Cadmium No-Bake 2023 Plating Solution

Overview

Cadmium No-Bake 2023 is a brush electroplating solution developed by SIFCO Process® for applying cadmium deposits without the need for post-plating hydrogen embrittlement relief baking. Designed for aircraft repair, maintenance and selective plating operations, it produces a medium-grey, matte cadmium coating with excellent process consistency across a wide operating range. The solution is particularly suited to touch-up repairs on aerospace components and can be used in accordance with major aerospace specifications where approved procedures are followed.

Application Guidelines

• Degrease the repair area using a residue-free solvent.
• Abrade the surface using 120-grit aluminium oxide paper or approved blasting media where specified.
• Rinse thoroughly with deionised water and dry before plating.
• Electroclean high-strength steels using the recommended SIFCO Process® cleaning solution where required.
• Begin plating at 6 V and increase gradually until slight burning is observed, then reduce by approximately 1 V for optimum deposition.
• When repairing vacuum deposited cadmium coatings, remove spilled solution immediately to prevent chemical attack.

Compatibility & Limitations

• Suitable for aluminium, steel, cast iron, nickel alloys, stainless steel and zinc alloys with appropriate preplate preparation.
• For hydrogen embrittlement-sensitive materials, follow applicable aerospace specifications.
• Do not reuse solution where prohibited by manufacturer or aerospace specifications.
• Excessive current density produces dark grey or black burned deposits.
• Conversion coatings may be applied after plating where required.

Packaging & Procurement

• Available through SIFCO Process® distribution network
• Recommended shelf life: 4 years
• Suitable for use with approved SIFCO Process® brush plating equipment and cover materials

Why This Product is Chosen for AOG / MRO
