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: Special hydroxysilanes, which can be obtained by reacting β-(3,4-epoxycyclohexyl)alkyltrialkoxysilanes with secondary amines, and adducts of the hydroxysilanes in the form of polymers containing silane groups. The hydroxysilanes can be produced having high purity in a simple process and are very stable in storage after production. The polymers containing silane groups that can be obtained by means of the hydroxysilanes have advantageous properties. The polymers enable moisture-curing compositions, which contain no isocyanate groups and which are suitable as elastic adhesives and sealants.

Abstract: The present invention relates to curing agents for epoxy resins including an alkylated polyethyleneimine. These curing agents have high functionality and a high content of secondary amino groups. Together with epoxy resins, they cure surprisingly quickly and without blushing effects even under humid and cold conditions to form films having very high cross-linking density. They are suited for coatings with high resistance requirements.

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: A composition containing calcium nitrate, at least one epoxy resin and at least one amine of formula (I). The composition allows the manufacture of low-emission epoxy-resin coatings that have good workability and that cure particularly rapidly in cold and damp conditions, without blushing-induced surface defects, thus achieving coatings of in particular high mechanical quality, with a minimal tendency to yellowing.

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: A two-component composition, containing at least one silane-group-containing polymer that is liquid at room temperature, at least one epoxide liquid resin, at least one polyetheramine, and at least one aminosilane or mercaptosilane. The composition has low odor, cures quickly and without blistering at room temperature, and, when cured, forms a tough elastic material of high strength, high adhesive force, and good thermal resistance that has no tendency toward yellowing or substrate discoloration. The composition is excellently suitable as a tough elastic adhesive for structural adhesive joints in the field of construction and in industrial production.
