COMPOSICAO MISTURA,PROCESSO E ARTIGO DE METAL |
摘要 |
<p>A composition which comprises (a) a salt of a metal (M) of a hydroxycarboxylic acid in which the OH and COOH groups are attached to the ring atoms of a fused ring system and (b) a surface coating compound or composition. The metal (M) is at least divalent and may be magnesium, calcium, barium or particularly zinc. The fused ring system is preferably a fused aromatic hydrocarbon ring system such as naphthalene. The OH and COOH groups can be attached to adjacent carbon atoms of fused hydrocarbon ring system. Zinc 3-hydroxy-2-naphthoate has been found to be particularly suitable. The composition may also include a metal oxide and/or a metal phosphate. Component (b) can be a film forming binder system, a natural oil or a grease. The composition can be coated onto the surface of a metal. The coated metal shows improved resistance to corrosion.</p> |
