Abstract: A process for the preparation of a coating, coated substrate, film or sheet, in which process a coating mixture comprising a reactive system of polyisocyanate-functional, a polyketone-functional, a polyepoxide-functional, a polyanhydride-functional and/or a poly carbonate-functional compound or polymer and a dispersion or fine powder of a compound containing a reactive hydrogen, which mixture is not or low reactive at room temperature, is applied onto a substrate, resulting in a substrate coated with the coating mixture, followed by reacting the compounds mentioned above by elevating the temperature, in a substrate coated with the coating mixture, followed by reacting the compounds mentioned above by elevating the temperature, in which the reaction temperature and consequently the reaction rate can be adjusted as desired by the addition of an additive to the coating mixture, or to one of the reactants of the coating mixture, prior to the mixing with the other component. According to the invention optionally a second reactive system is present and both systems are essentially reacted as a sequential two step reaction and between these reaction steps the coating is remoulded. The invention further comprises a product obtained by the process.

Abstract: A process for the preparation of a coating, a coated substrate, an adhesive, film or sheet or the like, which process comprises the application of a coating mixture containing a reactive system onto a substrate. According to the invention a coating mixture is used which comprising at least two reactive system and after application of the coating mixture the first reactive system is substantially reacted under conditions where the second reactive system is substantially not reacted. Thereafter the coated substrate is remoulded at elevated temperature and the second reactive system is substantially reacted during or after the remoulding of the coated substrate resulting in a fixed remoulded coating.
