1. Ethylenethiourea N 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. Ethylenethiourea N 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 Ethylenethiourea 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. Ethylenethiourea N is use as an accelerator for synthetic rubber.
