USE OF SUBSTITUTED HYDROXYLAMINES IN METAL PHOSPHATING PROCESSES |
| 摘要 |
Alkyl-substituted hydroxylamines are useful as aids in the phosphating of metal substrates. In particular, the rate of phosphating and the rate at which manganese compounds are dissolved into aqueous phosphoric acid solutions may be accelerated by alkyl-substituted hydroxylamines.
