PhosblackⅢPRODUCT INFORMATION
Scratch-resistant black electroless plating that can be applied to complex shapes
Functions / characteristics
Processable size（mm）
350×800×800
Processable materials
Iron, Stainless, Copper alloy, Aluminum alloy, etc.
Characteristics
- Glossy black electroless plating.
- Excellent heat and light resistance.
- Harder and scratch-resistant is better than other black coatings.
- It has a uniform coating even so complicated shape.
- No environmentally regulated substances such as chromium and lead are used.
Characteristics
| Light absorption | Absorbs about 90% of the light in the visible light range (380-750 nm) on average. |
|---|---|
| Heat resistance | Even after being held at 300°C for 2 hours, the reflectance does not changes much. |
| Accuracy | It has a uniform coating even so complicated shape. |
| Materials | A variety of materials can be treated. Please contact us for details. |
TEST DATA
Light absorption
Test method
An integrating sphere was attached to a spectrophotometer to measure the total light absorption.
Equipment used: Hitachi High-Tech U-3900 with 150mm diameter integrating sphere
Measurement range: 200 to 800 nm
Measurement light source: D2 lamp (200 to 340 nm), tungsten lamp (340 to 800 nm)
Result
PhosblackIII absorbed 91% of the light in the visible light range.
Heat resistance
Test method
PhosbrackIII and black anodized aluminum were heated at 300℃ for 2 hours, and the light absorption in the visible range before and after heating was compared.
Equipment used: Hitachi High-Tech U-3900 with 150mm diameter integrating sphere
Measurement range: 200 to 800 nm
Measurement light source: D2 lamp (200 to 340 nm), tungsten lamp (340 to 800 nm)
Result
PhosblackⅢ
Before heating : 91% → After heating : 90% ⇒ 1% lower
Black alumite (Black anodized aluminum)
Before heating : 91% → After heating : 78% ⇒ 13% lower
The light absorption rate of black alumina decreased by about 13%, on the other hand PhosblackⅢdecreased by about 1%.
Surface observation
Test method
The surface of PhosblackⅢ was observed by SEM.
Equipment used: JEOL S-4800
Result
Cracks of various sizes were observed on the surface.
(Crack width: 50 to 200 nm)
