Coatings utilized in multilayer sheets such as laminated films used for photovoltaic backsheets can be prepared by adding epoxy and carbodiimide to a polyurethane mixture to be utilized as the adhesive, prior to application of the coating to a substrate. Such coatings can exhibit improved resistance to hydrolysis, and can maintain bond strength under prolonged conditions of high heat and humidity. |
