Abstract: It is disclosed a process in continuous for the production of film/leaves or composites comprising the following phases a) preparation of a bi-component mixture to spread and feeding of the mixture to the spreading phase wherein the mixture is prepared, fed and disposed in continuous, in the pot-life time of the mixture itself; b) spreading of the mixture on at least a substrate, wherein the spreading on the substrate and the transport to the crosslinking phase are completed in the pot-life time of the mixture; c) crosslinking of the layer of mixture on said substrate carried out under static condition of the environment and at a variable temperature comprised between 50° C. and 100° C., with control of the temperature value of the coated product carried out in continuous, wherein the transport of the substrate spread during the crosslinking phase is achieved with the substrate spread under flatness conditions. The related apparatus is also disclosed.
