摘要:
The invention relates to the use of dithiophosphinic acids of general formula HS2P(R1)(R2) and/or its salts for producing anti-corrosion coatings on metallic surfaces, said coatings containing polymers and being devoid of chrome. In said formula R1 and R2 independently of one another represent organic groups with between 1 and 30 C atoms.
摘要:
The invention relates to a mehtod for applying integrated pre-treatment layers to metallic surfaces, especially the surfaces of strip metals, by treatment with a composition containing at least one binding agent, a cross-linking agent, a fine-particle inorganic filler, and compounds comprising at least two thioamide groups or one thioamide group and at least one functional group. The invention also relates to an integrated pre-treatment layer obtained by means of the inventive method.
