    Abstract: A process for preparing a curing agent for epoxy resins, in which an amine mixture including at least one parent amine of the formula (I) and at least one alkylated amine of the formula (II) is reacted or adducted with at least one glycidyl ether of the formula (III). The amine mixture is especially a reaction mixture from the partial alkylation of the amine of the formula (I). The process described enables, with low energy expenditure and high space-time yield, curing agents of low odor, low toxicity, low viscosity and high reactivity for epoxy resins and epoxy resin products that cure rapidly at ambient temperatures and especially also under cold conditions and at the same time enable high-quality coatings having an even, shiny surface.

    Abstract: An epoxy resin composition, the curing components of which contain at least one amine of formula (I) and optionally at least one amine A which is, in particular, an adduct of a polyamine and an epoxide. The amine for formula (I) is used in particular in the form of a reaction product of the reductive alkylation of 1,2-ethylenediamine and an aldehyde or ketone. The epoxy resin composition is used in particular as a low-emission, room-temperature-curing epoxy-resin coating. It is characterised by good processibility, quick curing, high hardness, a nice surface and a low tendency to yellowing.

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

    Abstract: The present invention relates to an amine of the formula (I) which is an adduct of 1,2-propylenediamine with an aryl monoglycidyl ether, to the use thereof as part of a hardener for epoxy resins, and to epoxy resin compositions obtained therewith. The amine of the formula (I) is preparable in a simple process in high purity, is of very low viscosity and is especially suitable for the curing of epoxy resins. It allows low-emission epoxy resin compositions which have good workability and which cure even under cold and damp conditions, quickly and without blushing effects, to form very hard products of high surface quality that display virtually no yellowing on exposure to light.

    Abstract: A method for producing a hot melt adhesive containing silane groups, in which at least one polyurethane polymer which contains isocyanate groups and is solid at room temperature is reacted with at least one hydroxysilane that is devoid of urea and thiourethane groups. The hot melt adhesive containing silane groups obtained from the method allows a low hazard classification, has a good degree of thermal resistance when melted such that, even upon application under prolonged heating, it does not tend towards premature thickening, releases no unpleasant odours, and crosslinks at room temperature without bubbles under the influence of moisture, resulting in an optically and mechanically high-quality and resistant adhesive connection.
