US Classification:

428414, 427508, 427514

Abstract:

Processes for coating substrates and the related substrates are disclosed herein. A one-component base coating composition is applied onto a substrate and a one-component top coating composition is applied wet-on-wet onto the applied base coating composition. The coating compositions are based on aqueous acrylate/polyurethane dispersions. The top coating composition is applied after the applied base coating composition develops a pendulum hardness of at least 50% of the pendulum hardness that would be exhibited by the base coating composition after UV cure. The applied coatings exposed to UV radiation to simultaneously cure both the base coating composition and the top coating composition.
