Download PDFExcellent values for friction coefficient reduction Combines properties that significantly improve the performance of plastic injection moulding tools
The coating is characterised by uniform layer thickness distribution and a low coefficient of friction, even with dry friction. Good resistance to sliding and abrasive wear and improved stick-slip behaviour are further positive properties. The coating has good corrosion resistance and is RoHS, Reach and CAprop65 compliant.
Corrosion and wear protection properties can be further improved by applying an electroplated or chemically deposited undercoating.
