| 摘要 |
Plasticizing resins, aqueous dispersions of cationic resins, and methods of making the same for use in cathodic electrodeposition are disclosed. The resins are formed from reacting a polyoxyalkylenepolyamine, a phenol, and a formaldehyde. The reactants may further include a block building unit derived from a polyepoxide. When used in combination with other conventional electrodepositable resins, deposited films with improved mechanical properties and decreased tendency toward cratering are obtained. |
