Abstract

Selon la présente invention, une matière active est parfaitement intégrée ou fixée à une couche adhésive autocollante sans réduire l’activité de cette matière. La présente invention concerne un procédé de production d’un enduit comprenant un substrat, une couche adhésive autocollante formée sur le substrat à laquelle une matière active est intégrée ou fixée, et une couverture superposée sur la couche adhésive. Le procédé consiste à former une couche adhésive de base autocollante sur un substrat ou une couverture par fusion de l’adhésif autocollant lui-même ou par évaporation d’un solvant utilisé avec chauffage simultané de cet adhésif en fonction de son type, et à intégrer ou fixer la matière active à la couche adhésive de base autocollante pour obtenir en continu un enduit, l’intégration ou la fixation de la matière active à la couche adhésive de base autocollante s’opérant après refroidissement de cette couche, initialement chauffée pour sa formation, à une température à laquelle l’activité de la matière active ne diminue pas.
