The invention relates to a method for coating a substrate, comprising the steps of: a) Applying a layer comprising a melamine-formaldehyde resin A to a substrate, whereby a coated substrate is formed; b) Optionally treating the coated substrate with IR- or NIR- radiation; c) Optionally applying an ink, dye solution or pigment dispersion to the coated substrate; d) Optionally applying a layer comprising a melamine-formaldehyde resin B to the coated substrate from step b) or c); e) Placing the coated substrate in a press; f) Optionally heating the coated substrate in the press for a certain amount of time; g) Increasing the pressure in the press and keeping the coated substrate under pressure for a certain amount of time. The invention further relates to a coated substrate as obtainable by the said method, and its use in a post- forming process.
La présente invention se rapporte à un procédé permettant de recouvrir un substrat et comportant les étapes suivantes: a) application d'une couche comportant une résine mélamine-formaldéhyde A sur un substrat, ceci permettant la formation d'un substrat recouvert; b) traitement facultatif du substrat recouvert au moyen d'un rayonnement IR ou NIR; c) application facultative d'une encre, d'une solution de colorant ou d'une dispersion de pigments sur le substrat recouvert; d) application facultative d'une couche comportant une résine mélamine-formaldéhyde B sur le substrat recouvert issu de l'étape b) ou c); e) placement du substrat recouvert dans une presse; f) chauffage facultatif du substrat recouvert dans la presse pendant un laps de temps donné; g) accroissement de la pression dans la presse et maintien du substrat recouvert sous pression pendant un laps de temps donné. L'invention se rapporte en outre à un substrat recouvert tel que pouvant être obtenu conformément audit procédé, et à son utilisation dans un processus de post-formage.
