Abstract

Se revela una combinacion de químicos adecuada para prolongar la vida en contenedor y reducir el tiempo de curado de una mezcla para contenedor de una composicion termofija. La combinacion de químicos incluye un catalizador, tal como dialurato de estaño de dibutilo; ácido carboxílico o sulfonico; y un compuesto de prolongacion, tal como 2,4 pentadiona. La combinacion es incluida por lo general en un componente polimérico de la composicion de uretano. La vida prolongada en contenedor proporciona al usuario un tiempo notorio más largo durante el cual puede aplicar eficientemente un recubrimiento de la mezcla en contenedor sobre una amplia variedad de superficies de substratos, mientras que además produce recubrimientos que curan rápidamente tras la aplicacion.
