Features of new IP black (PVD)
- Ion plating coating (PVD) with the highest blackness ever (Lab color space about L*35)
- Hard coating that can withstand bending tests and impact tests
- Incomparably superior wear resistance compared to wet plating
- High corrosion resistance that does not discolor or corrode even during long-term CASS tests and salt spray tests
