Functions and Uses：
1. DU-251 is a mild and multi-functional hot dipping electrolytic degreasing powder specifically formulated for copper alloys.
2. Strong emulsifying capacity and extraordinary serving lifetime.
3. Less foam generation, easy to clean and capable to reduce the carry over pollutions.
4. DU-251 is usually used in the hot alkaline dipping and the electrolytic cleaning, and it is especially suitable for the steel, iron, copper and brass. It is particularly effective for degreasing different metals in one same solution.
5. It contains surfactants. Excellent acid & alkali resistance and thermal stability. Extraordinary serving lifetime.
