METHOD FOR PRODUCING AN ANTICORROSION COATING
收藏资源简介:
The present invention relates to a method for producing an anticorrosion coating, in which (1) an anticorrosion priming agent containing (A) at least one organic resin as a binder and (B) at least one synthetic, layered double hydroxide that contains organic anions is applied directly to a metallic substrate, and (2) a polymer film is formed from the anticorrosion priming agent applied in step (1), the method being characterised in that the at least one synthetic, layered double hydroxide (B) comprises at least one organic anion of the following formula (I): where R1=COO-, SO3 -, R2/R3 = NH2, OH, H. The present invention additionally relates to coated metallic substrates that have been coated according to the method of the invention. The present invention also relates to the use of the anticorrosion priming agent that is to be used in the method of the invention for improving the corrosion resistance of metallic substrates.
