Abstract
1371913 Pre-treatment and electroless plating of plastics SCHERING AG 19 Oct 1971 [23 Oct 1970] 48580/71 Heading C7F An ABS plastics, modified polyolefin, polymer of an ester of acrylic acid, or polyamide, is pretreated for electroless plating by (i) treating with chromosulphuric acid, (ii) activating and (iii) treating with an aqueous solution containing a boron hydride compound. Steps (i) and (ii) may be separate, or simultaneous using CrO 3 /H 2 SO 4 / PdCl 2 with or without H 3 PO 4 . The boron hydride compound may be NaBH 4 , or R<SP>1</SP> R<SP>2</SP>R<SP>3</SP>NBH 3 where R<SP>1</SP> = lower alkyl and R<SP>2</SP>, R<SP>3</SP> = H or lower alkyl, and may be used in concentration 0À0001 to 0À1 mole/l, or in the case of subsequent Ni plating, the solution may also contain 0À1-0À5 mole/l of the reducing agent to be used in the Ni bath, e.g. NaH 2 PO 2 , in which case the amount of B compound may be as low as 0À00005 mole/l; the treatment temperature is 25-50C and the solution may also contain N 2 H 4 .H 2 O. The electroless Ni bath may contain 20-30 g/l Ni salt, e.g. NiSO 4 , 40-70 g/l complex former/buffer, e.g. citric or succinic acid, and 10-30 g/l alkali metal hypophosphite, e.g. NaH 2 PO 2 ; an electrolytic layer may be applied to the electroless Ni.
