(Dimethylaminoalkyl)carboxylic and -carbamic acid esters and (dimethylaminoalkyl) ethers and ureas are compounds which are especially suitable for use as amine curing agents for polyepoxide compounds. They impart longer curing times to the curable mixtures and thus good processing properties, especially when the mixtures are used as adhesives. In addition, the mechanical properties are often improved. Further, these compounds afford advantages when used as curing agents on account of their low volatility.
