Title
(EN) SILANE TREATMENT FOR ELECTROCOATED METALS
(FR) TRAITEMENT AUX SILANES DE METAUX REVETUS PAR ELECTRODEPOSITION
Abstract
(EN)
A method of treating a metal substrate by applying a coating of a silane solution comprising at least one bis-silyl aminosilane which has been at least partially hydrolyzed and at least one bis-silyl polysulfur silane which has been at least partially hydrolyzed. The silane coating provides corrosion resistance, as well as improved adhesion to electrocoats and other polymers. A silane coated metal substrate, as well as a silane solution, are also provided.
(FR)
La présente invention concerne une technique de traitement d'un substrat métallique par application d'un revêtement à base d'une solution de silane comprenant au moins un bis-silyle-aminosilane qui a été au moins partiellement hydrolysé et au moins un bis-silyle-polysulfure-silane qui a été au moins partiellement hydrolysé. Le revêtement de silane confère une résistance à la corrosion ainsi qu'une meilleure adhésion sur les revêtements par électrodéposition et sur les autres polymères. L'invention concerne également un substrat métallique revêtu de silane, ainsi qu'une solution de silane.
