摘要:
Disclosed are novel Mannich bases which are produced by using at least one phenolic compound of formula (I), formaldehyde, and at least one polyamine. Also disclosed is a two-step method for producing Mannich bases, by means of which low viscous Mannich bases are obtained.

摘要:
The invention relates to two-component epoxy resin compositions which contain at least one Mannich base in the hardener component and are provided with a glass transition temperature of more than 80° C. after being cured at a temperature ranging between 5° C. and 60° C. The inventive two-component epoxy resin compositions are used especially as adhesives.
