CURING AGENTS FOR LOW-EMISSION EPOXY RESIN PRODUCTS

摘要

The invention relates to hardeners for epoxy resins containing at least one adduct consisting 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 form hydroxyl groups. Said hardener has a low viscosity and hardens quickly together with the epoxy resins, even in moist, cold conditions, and without blushing to form films with high hardness and low brittleness. It is particularly suitable for low-emission, room temperature hardening coatings.
