Neutralizer PM-952 may be used with the Crownplate Process or PM System for plating-on-plastics and specifically for plating Noryl straight thru. When used after the rinses following chromic acid etch, Neutralizer PM-952 removes residual hexavalent chromium and prepares the etched plastic surfaces for catalyzation. The slightly alkaline neutralizer must be thoroughly rinsed from the parts prior to catalyst treatment.
- Complete catalysis of difficult to plate plastics
- Allows use of dilute catalyst baths
- Control of rack plating
