Abstract

Procedimiento para la obtención de materiales espumados a base de poliisocianato con una superficie de cobertura compacta, estable a la luz y al amarilleamiento, a base de poliuretano, por espumación de una mezcla de reacción que conduce a un material espumado a base de poliisocianato, en un molde cerrado, cuyas paredes interiores están cubiertas como mínimo parcialmente con la mencionada capa de cobertura o una mezcla de reacción que reacciona a dicha capa de cobertura, caracterizado porque antes de llenar el molde con la mezcla de reacción espumable las paredes interiores del molde se recubren, como mínimo parcialmente, con un agente de recubrimiento que reacciona a una capa de cobertura resistente a la luz y al amarilleamiento a base de poliuretano-poliurea, conteniendo aglutinante líquido, así como en caso dado disolvente, agente fluidificador, agente espesador, agente desmoldeador, pigmentos y/o otros agentes auxiliares en sí conocidos en la tecnología de las lacas, componiéndose el aglutinante esencialmente de a) como mínimo un prepolímero de NCO conteniendo como mínimo grupos isocianato enlazados exclusivamente en forma alifática y/o cicloalifática y b) una mezcla de endurecedor compuesta de poliaminas primarias presentes parcialmente en forma bloqueada de aldimina o cetimina, con grupos amino alifática y/o cicloalifáticamente ligados y agua.
