Method for treating the surface of a substrate based on sulphur polymer, intended to be covered with a coating

摘要

The invention relates to a method for treating at least one surface of a substrate based on sulphur polymer intended to be covered with a coating, said method comprising, prior to depositing the coating onto the surface of the substrate, a step of bringing the surface of the substrate into contact with a treating composition comprising at least one reducing agent.

主权项

1. A method for coating at least one surface of a substrate comprising a sulphur polymer, comprising, prior to depositing the coating onto the surface of the substrate, a treating step of said surface using a treating composition comprising at least one reducing agent which is able to reduce C—S, S—S, CON bonds and salts in the sulphur polymer forming the substrate, causing the sulphur polymer to functionalize through the creation of SH bonds near the surface by contact with the reducing agent,
wherein the treating step comprises at least the steps of: dipping the substrate into at least a bath comprising the treating composition, and rinsing off the substrate by dipping it into a deionized water bath.
