FIELD: chemistry.SUBSTANCE: epoxy composition contains the following (pts.wt): epoxy-diane resin or epoxy-novolak resin 100, anhydride curing agent 75-100 and curing accelerator 4-4.4. The curing accelerator is a latent initiator I-120U, which is a complex of caprolactam with zinc chloride and water. The curing accelerator is obtained with the following ratio of components, pts.wt: ?-caprolactam 100, zinc chloride 90-100, water 20-25.EFFECT: invention significantly lowers temperature and curing time without deterioration of thermophysical and deformation-strength properties of the epoxy composition.3 cl, 2 tbl, 15 ex |
