Abstract

Se fabrican espumas duras, esencialmente de célula cerrada que exhiben grupos uretano, urea y biuret, con adherencia sobresaliente a superficies solidas, mediante transformacion de a) poliisocianatos orgánicos, con b) aceite de ricino modificado, en presencia de c) catalizadores, y d) agua y, dado el caso, hidrocarburos de bajo punto de ebullicion como expansionantes y, dado el caso, en presencia de e) sustancias coadyuvantes y/o aditivos, empleándose como aceite de ricino modificado, productos de transformacion de aceite de ricino, aminas y/o compuestos hidroxilados, de un índice de OH entre 200 a 500, preferiblemente de 350 hasta 480.
