The provided epoxy tape includes a curative layer. The curative layer includes a scrim, a binder layer at least partially enclosing the scrim, and a latent curative dispersed in the binder layer. The curative layer is coated and then dried of solvent. Then an epoxy layer is laminated to a top and a bottom of the curative layer. The epoxy tape is placed between two parts being bonded together and then heated to temperatures of bottom up to about 110° C. to activate and disperse the active curative. A semi-structural bond is formed. Also, a method of making the epoxy tape is provided.
