Ultra Yellow
E-Chrome Ultra Yellow – High Corrosion resistant trivalent chromate. E-Chrome Ultra Yellow is a two part iridescent trivalent chromate that provides up to 150 hours salt spray resistance to white corrosion with out a topcoat. It does not rub off like other yellow trivalent chromates as it will pass the thumb test. E- Chrome Ultra Yellow offers more UV protection and does not fade in the sun like other yellow trivalent chromates.

The greatest benefit of E-Chrome Ultra Yellow is that it can be baked for hydrogen embrittlement (375º F 4-24 hours) without the color fading. After baking this corrosion resistance to white rust almost doubles to 300 hours!
