<p>An electroless plating solution contains H2O, H2O-sol. metal salt (pref. =80 gm. metal ion/100 ml), an acid component (pref. >1 gm. acid/100 ml) and >=5gm/100 ml H2O-sol carbohydrate (5 - 80 gm/100 ml. preferably 15 - 20 gm/100 ml.), and pref. 0.001 - 0.1 gm. phytol or guanylic acid being preferably included. The carbohydrate is preferably a mono-, di- or poly-saccharides, particular sucrose. The pH is pref. 1-4. The solution is used to plate metals (steel), plastic and ceramic materials. A uniform coating is obtained, even on irregular surfaces.</p> |
