【Abstract】 It is a new and environmental-protecting surface-treatment technology to apply silane coupling agents in metal pretreatment, which can obviously improve the adhesion and the anti-corrosion of coatings. The conventional chromating and phosphating processes can be replaced by it. The structure, the affecting mechanism and the optimum of silane, the preparation of solution, treatments of metals in solution of silane, the films and its analysis were summarized in this paper.更多还原
