| abstract |
The present invention relates to curing agents for epoxy resins containing at least one adduct of a primary diamine and an aromatic monoepoxide, at least one primary diamine and at least one secondary diamine which is free of primary amino groups and free of hydroxyl groups. The hardener is low viscous and, together with epoxy resins, hardens quickly and without blushing effects into films of high hardness and low brittleness, even in damp, cold conditions. It is particularly suitable for low-emission room temperature curing coatings. |
