MULTI-COMPONENT EPOXY RESIN COMPOSITION

摘要

The invention relates to multi-component epoxy resin compositions, comprising the following components: a) at least one epoxy resin component containing a1) at least one epoxy resin and a2) at least one compound of the general formula (I), wherein R1 and R2 independently from one another stand for hydrogen, C1-C6-alkyl, C1 -C4-alkoxy-C1-C4-alkyl, C5-C6-cycloalkyl, phenyl, phenyl-C1-C4-alkyl, C2-C6-alkenyl, or C2-C6-alkynyl, or R1 and R2 jointly stand for a C3-C11 alkylene group; R3 and R4 independently from one another stand for hydrogen, C1-C6-alkyl, C1-C4-alkoxy-C1-C4-alkyl, C5-C6-cycloalkyl, phenyl, phenyl-C1-C4-alkyl, C2-C6-alkenyl, or C2-C6-alkynyl, or R3 and R4 jointly stand for a C4-C6 alkylene group; b) at least one hardener component containing b1) at least one amine curing agent, wherein the epoxy resin component (a) and/or the hardener component (b) contain at least one additional constituent part c1), which is selected from aliphatic polyether polyols and aliphatic polyetheramine polyols. Multi-component epoxy resin compositions are suited for injection mortar systems, in particular for chemical fixing or anchoring systems.
