Abstract: The present invention relates to curing agents for epoxy resins, containing at least one adduct of trimethylhexamethylenediamine and cresyl glycidyl ether. The curing agent has a low viscosity and cures quickly together with epoxy resins even in moist, cold conditions and without blushing to form films with a high hardness and surface quality, which scarcely undergo yellowing upon exposure to light. It is particularly suited for low-emission room temperature-curing coatings.

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.

Abstract: Special hydroxysilanes, which can be obtained by reacting ?-(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: An amine of the formula (I) and a process for its preparation by reductive alkylation of 1,2-propylenediamine with a di- or trifunctional carbonyl compound and hydrogen. The amine of the formula (I) is low in viscosity and in odour, high in reactivity towards epoxides and outstanding in its compatibility with other amines and with epoxy resins. The amine of the formula (I) allows access to low-emission epoxy resin compositions which have good processing qualities, cure rapidly even at low temperatures and form high-quality, high-hardness plastics having an attractive surface.

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 odour 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: 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, are disclosed. 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: An amine which can be used in epoxy resin compositions that cure at room temperature. The amine dilutes the composition highly effectively, allows rapid, trouble-free curing, even in cold and damp conditions, and reduces brittleness. The amine is particularly suitable as a constituent of a curing agent for low-emission epoxy resin compositions that cure at room temperature, in particular for floor coverings.

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: The present disclosure relates to a two-component composition containing a polymer polyol, a dial chain extender, an aldimine of formula (I), optionally additional polyols and diphenylmethandiisocyanates in the two components. The composition is particularly suitable as a manually applicable solvent-free liquid film for coating and/or sealing floors and roofs. It also has a long open time, cures quickly and without complications in a wide temperature and humidity range, has a high level of strength and is weather resistant.

Abstract: The invention relates to polymers containing silane groups, to a method for their production and to their use as a component of curable compositions, in particular of moisture-curing sealants, adhesives or coatings that can be applied at ambient temperature, or of hot-melt adhesives containing silane groups. The polymers containing silane groups are obtained in particular by means of a special hydroxysilane which can be produced in particular from the reaction of lactides with aminosilanes.

Production from the reaction of lactides with aminosilanes is particularly advantageous. Hydroxysilane of formula (I), where n is 1 or 2.

Abstract: The present invention relates to curing agents for epoxy resins including an alkylated polyethyleneimine.

Abstract: The present invention concerns a low-odor, low-viscosity hardener for epoxy resins comprising the amine of formula (I), as well as a method for thinning of hardeners for epoxy resins by adding the amine of formula (I).

They are especially suitable for low-emission coatings.
