Summary The BY3 (Y=F, Cl, Br, I, NCS, H) adducts with the tertiary amines N,N-dimethyl-n-octylamine (DMOA) and N,N-dimethyl-benzylamine (DMOA) were prepared, characterized and tested as catalytic curing agents for epoxy (DGEBA) and epoxy-isocyanate resins. Evaluation of the storage stability and reactivity of the resins showed that the BBr3, BCl3, BI3 and B(NCS)3 adducts were good latent catalysts. No correlation could be found between the temperature of decomposition of the catalysts in an inert atmophere or in contact with air and the catalytic properties. Consequently the reaction medium was involved in the activation process.
