Title (EN) ADHESIVE COMPOSITION
(FR) COMPOSITION ADHESIVE
Abstract:
(EN) An adhesive composition is prepared from a major portion of (1) a carboxyl group-containing adhesive component having a weight average molecular weight of 800,000 or greater and a smaller amount of (2) an amino group-containing adhesion-improving component having a weight average molecular weight of 100,000 or less which is added to cross-link the component (1). The adhesive composition possesses excellent compatibility, transparency, and adhesive characteristics for plastics under normal and high temperatures, while controlling blistering, and is useful for producing plastic adhesive sheets, plastic protective sheets, adhesive tapes, double-coated adhesive tapes, adhesive labels, or protective films for plastics, as well as for ordinary adhesive agent for plastics.
(FR) Cette composition adhésive est élaborée à partir, en majeure proportion, (1), d'un composant adhésif renfermant un groupe carboxyle, d'un poids moléculaire moyen en poids égal ou supérieur à 800 000, et, en quantité plus réduite, (2), d'un composant améliorant l'adhérence qui renferme un groupe amino, d'un poids moléculaire moyen en poids égale ou inférieur à 100 000, composant que l'on ajoute aux fins de la réticulation du premier (1). Cette composition adhésive, qui présente de remarquables caractéristiques de transparence, d'adhérence et de compatibilité avec les plastiques et ce, à des températures normales ou élevées, permet d'éviter la formation de poches. Elle se révèle utile dans le cadre de la production de feuilles plastiques adhésives, de feuilles plastiques de protection, de rubans adhésifs, de rubans adhésifs à double enduisage, d'étiquettes adhésives ou de films protecteurs pour matières plastiques ainsi que comme agent adhésif courant pour matières plastiques.
