ことはできなかつ念のである。On the other hand, a low-temperature sealing agent using a metal fluoride was also developed, but because it uses a fluoride compound and a nickel compound as a base,
There is a fatal flaw that causes the aluminum anodic oxide film to turn green. In addition, if the sealing temperature is 35°C or higher, the sealing time is 20 minutes or more, and the - of the sealing solution is 6.5 or higher, powdering tends to occur on the surface of the aluminum anodic oxide film. There is also. As described above, this low-temperature piercing treatment agent cannot be used for a wide range of aluminum products because it causes a change in color tone and the sealing treatment conditions are limited.

理を行うことができるようになったのである。Low-temperature sealing agents based on metal fluorides, i.e., fluorine compounds and nickel compounds, have the disadvantage of greening the anodic oxide film of aluminum and aluminum alloys, and the color tone changes particularly when the alumite film thickness exceeds 15 μm. , its scope of use was limited. However, the inventors
By adding a water-soluble cobalt compound to nickel fluoride or a combination product of a fluorine compound and a nickel compound in an amount of 10 to 40 wt. It has been discovered that low-temperature sealing treatment can be performed with almost no decrease in the properties. Therefore, with this invention, it has become possible to perform low-temperature sealing treatment on a wide range of aluminum and aluminum alloy products.
