EPIKURE™ Curing Agent 3046 is an aliphatic amidoamine that provides a working life of several hours at normal room temperatures, yet cures to handling strength in thin sections overnight at temperatures above 60 °F. Good strength properties are generally achieved within three days and an essentially complete cure is obtained within two weeks at room temperature.
The useful combining ratio with EPON™ Resin 828, varying from 35 to 100 parts per 100 parts resin, makes EPIKURE Curing Agent 3046 a very versatile ambient temperature curing agent.
Optimum properties are obtained at 50 parts per 100 parts resin in combination with an unmodified epoxy resin such as EPON Resin 828. Although the heat deflection temperature is improved with an elevated temperature post cure, most other properties are as good or slightly better in a room temperature cure; impact resistance is particularly high.
