MEJORAS A COMPOSICIONES ELECTRODEPOSITABLES CATIONICAS A TRAVES DEL USO DE ACIDO SULFAMICO Y DE DERIVADOS DEL MISMO

A cationic electrodepositable composition containing a resinous phase dispersed in an aqueous medium is disclosed. The resinous phase has basic nitrogen groups which are at least partially neutralized with sulfamic acid or a derivative thereof, that is, an acid of the formula: H - @ - SO3H where R i...

Zusammenfassung:	A cationic electrodepositable composition containing a resinous phase dispersed in an aqueous medium is disclosed. The resinous phase has basic nitrogen groups which are at least partially neutralized with sulfamic acid or a derivative thereof, that is, an acid of the formula: H - @ - SO3H where R is H or C1 to C4 alkyl. The compositions are in the form of relatively small particle size aqueous dispersions, and when used in the process of cationic electrodeposition, enable the formation of thick films with high throwpower. Also, the use of sulfamic acid passivates the anode.
