Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A curing agent, suitable for curing epoxy resins, comprising an amine of formula (I) and at least one polyamine A which has at least three epoxide group-reactive amine hydrogens, wherein the polyamine A is an adduct with an epoxide. 2. A curing agent, suitable for curing epoxy resins, comprising an amine of formula (I) and at least one polyamine A which has at least three epoxide group-reactive amine hydrogens, wherein the polyamine A is an adduct with an aromatic monoepoxide. 3. An epoxy resin composition containing at least one epoxy resin and one curing agent suitable for curing epoxy resins, wherein the curing agent comprises an amine of formula (I) and at least one polyamine A which has at least three epoxide group-reactive amine hydrogens, 4. The epoxy resin composition according to claim 3 , wherein the epoxy resin is a liquid resin that is a glycidyl ether of a bisphenol. 5. A cured composition obtained from curing the composition according to claim 3 . 6. An article containing the cured composition according to claim 5 . 7. An epoxy resin composition, wherein it is a two-component composition, comprising: (i) a resin component containing at least one epoxy resin, and (ii) a curing agent component containing an amine of formula (I):
