.Features:
Aluminum alloy acidic descaling agent is an excellent descaling liquid, which provides a uniform and dense substrate surface for subsequent electroplating and can obtain good coating adhesion.
Very little gas is released during operation, which is beneficial to environmental protection.
Especially suitable for aluminum alloys with high silicon content (such as 3, etc.).
It is not recommended to be used in aluminum alloys with a copper content greater than 3% (such as:, series aluminum alloys and some series of forged aluminum) and 3 cast aluminum.

3. Preparation of the solution:
When opening the cylinder, add the ingredients in the order in the table and pour them into the tank, stir gently, and cut. Don't cheer up.
Do not add acid or other raw materials, otherwise unpredictable chemical reactions may occur.
The processing time should be calculated by calculating the immersion time and the air exposure time before being transferred to water washing after leaving the bath. Depending on the aluminum alloy material and operating temperature, the immersion time is generally between minutes, and the air exposure time does not exceed seconds.
Do not add water to this solution.
