Abstract
An adhesion-active heat-protective coating based on an epoxyurethane oligomer, an aromatic amine-curing agent, benzoic acid as a curing accelerator, and melamine polyphosphate as a filler was developed. The curing regularities of the coating were studied, and its mechanical, thermal, and adhesion characteristics, as well as its sorption properties and glass-transition point, were determined.
