Abstract

Procedimiento para recubrir directamente o por inversión sustratos con un sistema de recubrimiento de dos componentes endurecible bajo calor, a base de poliuretano, como capa de cobertura, de adhesión o de espuma, caracterizado porque a) un prepolímero conteniendo en promedio 2-4 grupos NCO aromáticos, bloqueados por cetoxima, con un peso molecular medio de 1000 - 15000, se hace reaccionar con b) un reticulador de fórmula **(Fórmula)** donde R significa hidrógeno o un grupo metilo, en caso dado en presencia de c) pigmentos, materiales de carga, agentes de propulsión y otros aditivos, en si conocidos, a una temperatura de unos 120 - 190ºC sobre el sustrato a recubrir, manteniendo la proporción de equivalencia entre grupos NCO bloqueados y grupos NH2 entre 1,35: 1 y 0,95 : 1, conteniendo la masa de recubrimiento en total como máximo un 15% en peso de disolventes orgánicos y estando libre de dispersiones acuosas de polímero o soluciones de polímero.
