Polyurethane–urea coatings derived from UV-cured polyurethane–urea acrylate transition coatings for enhanced resistance to chemical warfare agent simulants

Ultraviolet (UV) cured polyurethane–urea acrylate (PUUA) with hindered urea were prepared to function as a transitional coating. Upon heat treatment, the PUUA network shifts to PUU defensive network with improved resistance.
