Abstract:
1. A composition comprising: at least one epoxide adduct A having on average more than one epoxide group per molecule; at least one polymer B of the formula (I) in which: the at least one polymer B has at least one aromatic structural element, which is bound in the polyurethane prepolymer via urethane groups; in which: wherein the at least one polymer B is obtained from the reaction of a monohydroxyepoxide of the formula (II) and of a linear or branched polyurethane prepolymer terminated with isocyanate groups of the formula (III) wherein the polyurethane prepolymer of the formula (III) is obtained from the reaction of at least one polyisocyanate, at least one isocyanate-reactive polymer and at least one, optionally substituted, phenol selected from the group consisting of 1,4-dihydroxybenzene, 1,3-dihydroxybenzene, 1,2-dihydroxybenzene, 1,3-dihydroxytoluene, 3,5-dihydroxybenzoates, bis(4-hydroxyphenyl)methane (bisphenol F), bis(4-hydroxyphenyl) sulfone (bisphenol S), naphthoresorcinol, dihydroxynaphthalene, dihydroxy-anthraquinone, dihydroxybiphenyl, 3,3-bis(p-hydroxyphenyl)phthalides, 5,5-bis(4-hydroxyphenyl)hexahydro-4,7-methanoindane, phenolphthalein, fluorescein, 4,4′-[bis(hydroxyphenyl)-1,3-phenylenebis(1-methylethylidene)] (bisphenol M), 4,4′-[bis-(hydroxyphenyl)-1,4-phenylenebis(1-methylethylidene)] (bisphenol P), o,o-diallylbisphenol A, dicresols prepared by reacting cresols with diisopropylidenebenzene, phloroglucinol, gallic ester, cresol novolacs having an —OH functionality of from 2.0 to 3.5, and isomers thereof, at least one thixotropic agent C based on a urea derivative in a nondiffusing carrier material; and at least one curing agent D for epoxy resins, which is activated by elevated temperature.
