摘要

Coating for alumu00ecnio, process for preparation of a coating to alumu00ecnio, coating process and coated alumu00ecnio alumu00ecnio. The present invention relates to a material useful as a coating of aluminum and its alloys, a process for their preparation, a process for coating of aluminium alloys and aluminium alloys coated.More specifically, the present invention relates to the synthesis of a salt containing two silu00edcios (organossilano polymerisable bis silane) and the group organic Diazabicyclo [2.2.2] octane.The present invention is an alternative environmentally friendly as pre treatment on aluminium alloys, in replacement of the conventional method of plating, not present toxicity and due to its high efficiency corrosion in aggressive media.
