Title (EN) PRIMER COMPOSITIONS FOR NON-STICK COATINGS AND METHOD FOR MANUFACTURING SAME
(FR) COMPOSITIONS DE PRIMAIRES DE REVÊTEMENTS ANTIADHÉSIFS ET LEUR PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) The present invention relates to a primer composition for a non-stick coating which includes a polyamide-amic acid having an acid value of 50 to 200 mg KOH/g, a Lewis base, water and at least 5 wt % of a polar aprotic solvent relative to the total weight of said composition. According to the invention, the weight ratio of PAI/polar aprotic solvent in said composition is at least 1.5. The present invention also relates to a method for preparing such a composition, and to a method for manufacturing an item comprising a metal substrate to which such a composition is applied.
(FR) La présente invention concerne une composition de primaire de revêtement antiadhésif comprenant un polyamide- acide amique ayant un indice d'acide compris entre 50 et 200 mg de KOH/g, une base de Lewis, de l'eau et moins de 5 % en poids d'un solvant aprotique polaire par rapport au poids total de ladite composition. Selon l'invention, le rapport massique PAI/solvant aprotique polaire dans ladite composition est d'au moins 1,5. La présente invention concerne également un procédé de préparation d'une telle composition, ainsi qu'un procédé de fabrication d'un article comportant un substrat métallique sur lequel on applique une telle composition.
