Abstract
Se describe un agente de reemplazo efectivo, ambientalmente inocuo, para la tiourea, para utilizarse como un agente complejo en los procesos de electrodeposición de desplazamiento, en los cuales la solución de electrodeposición se aplica a la superficie del substrato que va a ser electrodepositada por inmersión o por rocío, en cascada, vaciado y similares. El agente complejo de reemplazo es un compuesto dialquilimidazol-2-tiona no simétrico, que tiene la fórmula I: en donde A es metilo o etilo, y cuando A es metilo, B es un grupo alquilo o cicloalquilo de 3 a 6 átomos de carbono, y cuando A es etilo, B es un grupo alquilo o cicloalquilo de 4 a 6 átomos de carbono. De esta clase de compuestos, se prefiere el 1-metil-3-propil-2-tiocarbonil-2,3-dihidroimidazol para la electrodeposición de estaño por inmersión. Esta clase de agentes complejos es particularmente útil en la electrodeposición de estaño de desplazamiento por rocío, para la fabricación de tableros de circuitos impresos, en donde el metal de estaño libre se adiciona a la solución de electrodeposición.
