It is a black plating technology performed by electroless plating.
Gives a piano black-like dark black film.
No environmentally regulated substances are used. (RoHS compliant product)

It is used for lens peripheral parts of optical equipment, semiconductor devices, cooling parts such as heat sinks, ultraviolet exposure devices, light-shielding covers, etc.

Maximum size that can be processed: 800 x 800 x 400 up to 50 kg

<Features>
・ The film thickness is uniform, and it can be applied evenly to parts with complicated shapes and the inner surface of pipes.
・ Excellent in wear resistance compared to other black surface treatments
・ High hardness and scratch resistance (around Hv500)
-Excellent in heat resistance and light resistance (no discoloration or fading due to UV irradiation)
・ Average reflectance in the visible light region (total reflection including diffusion) less than 10%
・ Because it is a conductive film, it does not carry static electricity.
・Not using environmentally regulated substances (RoHS compliant)

<Characteristics>
● Light absorption: Absorbs 90% or more of light in the visible light region (380 to 750 nm) on average.
● Corrosion resistance: No corrosion even after 150 hours of continuous 5% salt spray test
● Heat resistance: The reflectance does not change even if it is held at 200 ° C for 2 hours.
● Precision: Uniform film formation is possible for all shapes (± 10% of the specified film thickness)
● Materials: Various materials can be processed.
