MEJORAS EN UN METODO PARA REVESTIR ARTICULOS CON UNA RESINA FORMADORA DE PELICULA

摘要

An improved method of coating objects in an aqueous cathodic electrodeposition bath. The use of volatile organic coalescent solvents is eliminated by using a blocked crosslinking agent which is the reaction product of a polyetherpolyol and a polyfunctional isocyanate. The coatings are smooth, flexible and have high film build.
