ELECTRODEPOSITABLE COATING COMPOSITIONS AND RELATED METHODS |
摘要 |
Provided is an electrodepositable coating composition of a resinous phase dispersed in an aqueous medium, the resinous phase including (a) an active hydrogen-containing, cationic salt group-containing resin; and (b) an at lea st partially blocked polyisocyanate curing agent. The composition contains an organotin catalyst which is or is derived from a dialkyltin compound having the structure (I): [R1][R2]- Sn = O where R1 and R2 are the same or differen t, and each independently represents a monovalent hydrocarbon group wherein the sum of the carbon atoms in R1 and R2 is greater than 8. The catalyst is present in an amount sufficient to effect cure at a temperature at or below 340~F (171.1~C). Methods of preparing and using the composition also are provided.
