The invention relates to the use of a block copolymer having at least one block that comprises phosphate and/or phosphonate functions, as an additive for film-forming compositions, such as paint, latex or mastic which is optionally siliconised in order to ensure or promote the adhesion of the aforementioned compositions on a metallic surface or to protect said metallic surface against corrosion. The invention also relates to film-forming compositions comprising the abovementioned block copolymers.
本发明涉及一种嵌段共聚物的用途,该嵌段共聚物至少有一个嵌段包含磷酸盐和/或膦 酸盐功能,可用作成膜组合物(如油漆、乳胶或胶泥)的添加剂,该成膜组合物可选择硅 化,以确保或促进上述组合物在金属表面的附着力,或保护所述金属表面免受腐蚀。本发明还涉及由上述嵌段共聚物组成的成膜组合物。
