| Bis-Benzene Sulfonylimide is used as a primary brightener in nickel baths at a concentration of 50-500ml/L. |
| As a plating intermediate, Bis-Benzene Sulfonylimide can use as additive for nickel plating bath; it can soften and brighten the plated hardware. |
| Bis-Benzene Sulfonylimide can also use as pharmaceutical intermediate. |
| It is used in additives for Nickel plating for improving ductility, tolerance to impurities and brightness. |
| In electroplating, it is used as primary brightener instead of saccharin; it has better leveling ability and less consumption than saccharin. |
| Store in cool place. Keep container tightly closed in a dry and well-ventilated place. |
| Plastic bag with fibers drum packaging (we can package depending upon customer requirements, e.g. 25, 50 or 200kg). |
