We have launched a new product: heated black dye "Ultra Black Super"!

The newly released "Ultra Black Super" is a revolutionary heated black dye that can finish steel, superalloys, and cast iron in deep black.
*Sample parts can also be tested for black dyeing.*
Traditionally, different agents were required for steel and cast iron, with cast iron tending to have a reddish hue. The new product "Ultra Black Super" allows for black dyeing using the same agent and boiling temperature, forming an excellent deep black magnetite (Fe3O4) coating.
Thanks to its superior oxidizing power, steel achieves a deeper black color. Even superhard alloys, which previously had poor dye adhesion, can now be finished in deep black.
The groundbreaking black dye "Ultra Black Super" supports the formation of more stable coatings and quality stability.
**Features**
- Forms a magnetite (Fe3O4) coating using the same agent and boiling temperature for both steel and cast iron.
- Generates less irritating mist, significantly reducing impact on human health.
- Improves the working environment.
- The thickness of the black dye coating, which corresponds to the surface gloss of the material, does not affect dimensional accuracy, is wear-resistant, and does not peel off when rubbed.
- The coating retains rust inhibitors, providing excellent rust prevention (indoors).
