Abstract: An amine of formula (I) in a curing agent for epoxy resins, a curing agent for epoxy resins containing the amine of formula (I) and resultant epoxy resin compositions which can be used particularly as low-emission room-temperature-curing epoxy resin coatings demonstrating good workability, rapid curing, a high degree of hardness and high surface quality. The amine of formula (I) is low-odour, can be handled well at room temperature even without dilution, and can be produced at high purity in a simple process.

Abstract: An amine of the formula (I) for use as hardener for epoxy resins, hardeners for epoxy resins containing the amine of the formula (I) and resultant epoxy resin compositions which more particularly can be used as low-emission room-temperature-curing epoxy-resin coatings with high hardness and surface quality. The amine of the formula (I) has little odor and is a very successful diluent for epoxy resin compositions. It is more particularly obtained by reductive alkylation from 1,2-propylenediamine and an aldehyde or ketone.

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 curing agent is of low viscosity and cures, together with epoxy resins, rapidly and without blushing, even under damp, cold conditions, to form films of high hardness and low brittleness. It is particularly well suited for low-emission coatings that cure at room temperature.

Abstract: The invention relates to hardeners for epoxy resin containing secondary amino groups having dialkyl amino phenyl groups. The hardeners have a surprisingly low viscosity and harden surprisingly fast together with the epoxy resins, even in moist, cold conditions, and without blushing to form films with high hardness and stability. They are suitable, in particular, for low-emission coatings.

Abstract: The present invention relates to hardeners for epoxy resins, which contain secondary amino groups having pyridinyl groups. They harden surprisingly quickly together with epoxy resins even under cold and humid conditions and without producing blushing to give films with a high degree of hardness, the highest degrees of hardness being obtained with a surprisingly low amount of hardener required. They are especially suitable for low-emission coatings with high resistance requirements.

Abstract: A curing agent for epoxy resins, containing at least one amine adduct of formula (I) which can be obtained as an addition product of a mixture of a primary diamine, a monoalkylated other diamine and a polyepoxide. The curing agent makes it possible to produce low-odor, low-emission epoxy resin products, in particular coatings, which have a surprisingly low viscosity, a high curing rate, a high final hardness, and a surprisingly appealing surface.

Abstract: A curing agent for epoxy resins, including at least one amine A1 of the formula (I) and at least one amine A2 which is a polyalkyleneamine or polyethyleneimine, where the weight ratio between amine A1 and amine A2 is in the range from 20/1 to 1/2. The curing agent of the invention enables inexpensive and low-emission epoxy resin products having good processability, long pot life, surprisingly rapid curing, especially also under cold conditions, high strength, high bond strengths, high glass transition temperature and a low tendency to yellowing, with formation of surprisingly nice surfaces having barely any blushing-related defects even in the case of two-dimensional application and under moist and cold conditions. Such epoxy resin products are advantageously usable as coating, especially for floors, or as adhesive.
