Abstract | An embodiment relates to a resin composition containing a tetraglycidyl amine; a bisphenol epoxy; a dicyandiamide; and an aromatic urea; wherein the tetraglycidyl amine has a EEW of 110 g/eq to 140 g/eq and is an amount of 30 to 60 PHR per 100 PHR of total epoxy resin in the resin composition; wherein the resin composition has a Tg of at least 160°C when cured at 143°C for 3 min and also maintains a Tg of greater than 160°C when cured at 177C for 1 min or longer.
Un mode de réalisation concerne une composition de résine contenant une amine de tétraglycidyle; une résine époxy à base de bisphénol; un dicyandiamide; et une urée aromatique; l'amine de tétraglycidyle ayant un EEW de 110 g/eq à 140 g/eq et représente une quantité de 30 à 60 PHR par 100 PHR de la résine époxy totale dans la composition de résine; la composition de résine a une Tg d'au moins 160°C lorsqu'elle est durcie à 143°C pendant 3 min et conserve également une Tg supérieure à 160°C lorsqu'elle est durcie à 177 °C pendant 1 min ou plus. |
