Summary:An improved aqueous electrocoating composition that contains an anticrater agent which is a reaction product of polyoxyalkylene diamine and isocyanato alkyl alkoxy silane which is hydrolyzed and has a number average molecular weight of about 2,000-5,000; electrodeposited finishes are formed that have a significant reduction in craters and are smooth and even finishes. Se describe una composicion de electrorrecubrimiento acuosa mejorada, que contiene un agente antidepresiones el cual es un producto de reaccion de polioxialquilen diamina e isocianato alqiul alcoxi silano, el cual es hidrolizado y tiene un numero de peso molecular promedio de aproximadamente 2000-5000; los terminados electrodepositados que se forman tienen una reduccion significativa en las depresiones y son terminados lisos y uniformes.
