More Information
Summary:A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and amidoamine and/or imidazoline crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show excellent resistance to deterioration of physical properties upon humid ageing. Una composición para hacer una espuma de poliuretano incluye un catalizador de uretano de amina terciaria no fugitivo y aditivos de reticulación de amidoamina y/o imidazolina. Las espumas preparadas de la reacción de un poliol y un isocianato orgánico en la presencia de estos ingredientes muestran excelente resistencia al deterioro de las propiedades físicas en el envejecimiento húmedo.
