The physicochemical, thermomechanical, and elastic-strength characteristics of samples based on an oligoetheracrylate binder cured both under the action of only coherent UV radiation and with subsequent aftercuring in a UV oven were studied. It was established by differential scanning calorimetry that full curing of the polymeric matrix is not achieved by coherent UV radiation. The use of additional treatment in a UV oven leads to the formation of a denser three-dimensional cross linking, which increases the brittleness of the polymeric matrix. The introduction of 16A electrocorundum as a filler into the polymeric matrix decreases the thermomechanical and elastic-strength characteristics of an oligoetheracrylate binder regardless of the curing mode.
