The durability of the thus obtained rust preventive coating was evaluated by JISZ2371 "Salt spray test method", and the time until white rust was generated was visually measured. In addition, about criteria, Examples 1-15
The same was done. The results are shown in Table 4-2.

年の環境問題等から、クロム処理をしないマグネシウム
材料用防錆剤として好ましく使用することができる。Since the rust inhibitor composition of the present invention is constituted as described above, it forms an organosilicon rust preventive film having excellent durability on a metal surface and is useful as a metal rust inhibitor. Particularly, in view of recent environmental problems, it can be preferably used as a rust preventive for a magnesium material which is not subjected to chromium treatment.
