PC-Grade Stabilized Peptone (PSP) is a purified, conditioned, and refined liquid Peptone for use in tin/lead fluoborate plating baths. PSP acts to improve throwing power, increase limiting current density, and refine grain structure during conventional 60/40 solder plating. It may be added on an ampere hour basis or controlled by Hull cell test.
- PSP is stabilized to improve shelf life.
- PSP is purified, reducing the odor and filterable solids present in many Peptone products.
- PSP can be added over-the-side to baths currently using conventional liquid Peptone.
