Use of guanidine derivatives as accelerators for hardening epoxy resin systems

摘要

Guanidine derivatives (I) are used as accelerators for hardening epoxy resin systems. Guanidine derivatives of formula (I) are used as accelerators for hardening epoxy resin systems. R 1>, R 2>H, 1-8C alkyl or phenyl; R 3>H, 1-8C alkyl or optionally substituted phenyl; X : O, S, NR 3> or N +>(R 3>) 2A ->; Z : C or P; Z : NR 1>R 2> or N=C(NR 1>R 2>) 2; n : 1 or 2; A : halide or other anion. An independent claim is also included for guanidine derivatives of formula (R 1>R 2>N) 2C=N-CX'-N=C(NR 1>R 2>) 2 (II) X' : O or S. [Image].
