Plastic surface treatment after etching with nitric acid medium |
| abstract |
The present invention discloses a method of electroplating a metal on a plastic substrate, particularly an ABS substrate, without using a chromium-containing etchant. The method comprises (i) etching the plastic substrate in an acidic solution of nitrate ions and preferably silver ions, (ii) conditioning the substrate in an aqueous solution comprising amine or ammonia, and (iii) activating the substrate. It is preferred to use a palladium activator, and (iv) to electroplate the substrate with an electroless plating solution. This method allows adhesive electrodeless plating of plastic substrates (especially ABS substrates) without the use of a chromium etchant. |
