Zusammenfassung: | A trimerization catalyst composition suitable for making a polyisocyanurate comprising (insulation) foam, said composition comprising at least a trimerization catalyst compound selected from one or more organic salts from alkoxides wherein said organic salt is selected from alkali metal, earth alkali metal, a transition metal such as Ti and/or quaternary ammonium organic salts.
L'invention concerne une composition de catalyseur de trimérisation adaptée pour fabriquer une mousse (isolante) comprenant du polyisocyanurate, ladite composition comprenant au moins un composé catalyseur de trimérisation choisi parmi un ou plusieurs sels organiques d'alcoxydes, ledit sel organique étant choisi parmi un métal alcalin, un métal alcalino-terreux, un métal de transition tel que Ti et/ou des sels organiques d'ammonium quaternaire. |
