What it is and what it does. Plating rack coating powder is the PVC plastisol powder used to insulate plating racks and jigs so that only the part, and not the rack, is plated.
- White to light grey fine powder, applied by heating the cleaned rack and dipping it into the fluidised powder bed.
- Proper insulation stops the rack from stealing current and from plating over, which causes burnt contact points and uneven deposits.
- The coating must be stripped back from the contact tips, otherwise the parts make no electrical contact.
Typical Use in a Plating / Finishing Line

| Coating | Preheat the rack to the supplier schedule, dip in the fluidised bed, then cure |
| Film thickness | Typically 0.5-1.5 mm depending on the rack and the process |
| Stripping | Mechanical or thermal stripping of the contact tips after coating |
| Control | Visual inspection plus an insulation check with the rack in the bath |

Buyer Questions We Answer Every Week
| Question | Answer |
|---|---|
| Why do the contacts plate over? | The plastisol has covered the contact tips; strip them back to bare copper before using the rack. |
| How long does the coating last? | Months to years depending on the bath chemistry; chromic acid and hot alkaline baths degrade it fastest. |
