Abstract

L'invention concerne un enduit d'acide polylactique et un procédé pour le préparer, consistant à placer un mélange maître d'acide polylactique et un solvant dans un réceptacle, à agiter le mélange jusqu'à dissolution complète du mélange maître d'acide polylactique et à former une dispersion transparente, puis à éliminer l'eau à l'aide de tamis moléculaires pour obtenir un enduit d'acide polylactique contenant approximativement 1-85% en poids de matière sèche.
