摘要: A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and an alkylated polyamine crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show improved resistance to deterioration of physical properties upon humid aging.
