1. As a brightener for copper plating, excellent results can be obtained by adding a very small amount of the brightener. Like M and N, the coating with good leveling and toughness can be plated in a wide temperature range.
2. N Ethylenethiourea is often used in conjunction with acid copper plating brightener M and SPS.When the content of N is too high, the coating will produce bright dendritic stripes, and the leveling performance will decline. Generally, SP, M or electrolytic treatment can be added.
3. When the content of N is too low, the brightness and leveling of the coating will decrease, especially the brightness of the low area will decrease or even become red.
4. Use as an accelerator for synthetic rubber.
