Title
(EN) SYSTEMS AND METHODS FOR LAMINATING CAN END STOCK
(FR) SYSTÈMES ET PROCÉDÉS DE STRATIFICATION DE TÔLE POUR EXTRÉMITÉS DE BOÎTES MÉTALLIQUES
Abstract
(EN)
Improved aluminum can end stock (CES) is disclosed. The CES includes an adhered polymer coating exhibiting low feathering and high performance in various acid tests. The low feathering and resistance to acid tests is accomplished by incorporating a copolymer adhesion promoter film to an aluminum alloy before lamination. In some cases, the metal strip is pretreated with a conversion layer, which can include compounds of trivalent chromium (Cr(III)) and phosphates or titanium and zirconium.
(FR)
L'invention porte sur tôle pour extrémités de boîtes métalliques (CES) améliorée, en aluminium. La CES comprend un revêtement polymère collé présentant un faible amincissement des bords et des performances élevées dans divers essais à l'acide. La faible amincissement et la résistance aux essais à l'acide sont réalisés par incorporation d'un flm promoteur d'adhérence, à base de copolymère, sur un alliage d'aluminium avant stratification. Dans certains cas, la bande métallique est prétraitée avec une couche de conversion, qui peut comprendre des composés de chrome trivalent (Cr (III)) et de phosphates ou de titane et de zirconium.
