Beschreibung
Zusammenfassung:	The invention is a composition comprising one or more epoxy resins; one or more rubber modified epoxy resins; one or more toughening compositions comprising the reaction product of one or more isocyanate terminated prepolymers and one or more capping compounds having one or more bisphenolic, phenolic, benzyl alcohol, aminophenyl or, benzylamino moieties wherein the reaction product is terminated with the capping compound; one or more curing agents and one or more catalysts for epoxy resins which initiates cure at a temperature of about 100°C or greater; and optionally; fillers, adhesion promoters, wetting agents and rheological additives useful in epoxy adhesive compositions. The composition can be used as an adhesive and applied as a stream using a high speed streaming process.
