Title (EN) USE OF A COATING COMPOSITION AND METHOD OF COATING A CAN
(FR) UTILISATION D'UNE COMPOSITION DE REVÊTEMENT ET PROCÉDÉ DE REVÊTEMENT D'UNE CANETTE
Abstract:
(EN) Use of a coating composition in the reduction or prevention of insufficient venting of a beverage can, the beverage can comprising a can body and a can end having a score line on said can end, wherein the coating composition comprises a polyester material, wherein the coating composition is applied to at least the internal surface of the can end over at least a portion of the score line, and wherein a cured film formed from the coating composition has a glass transition temperature (Tg) of at least 50°C. A method of coating a can comprising a can body and a can end having a score line on said can end, wherein the method comprises applying a coating composition to at least a portion of an internal surface of the can end over at least a portion of the score line, the coating composition comprising a polyester material; and curing the coating composition to form a cured film, wherein the cured film has a glass transition temperature (Tg) of at least 50°C, wherein the can, when filled with a carbonated beverage and sealed, exhibits sufficient venting upon rupture of the score line.
(FR) L'invention concerne l’utilisation d'une composition de revêtement dans la réduction ou la prévention d'une création de vide par ventilation insuffisante d'une canette de boisson. La canette de boisson comprend un corps de canette et une extrémité de canette, ladite extrémité de canette comportant un trait de coupe. La composition de revêtement comprend un matériau polyester et est appliquée sur au moins la surface interne de l'extrémité de canette en recouvrant au moins une partie du trait de coupe, un film durci constitué de la composition de revêtement présentant une température de transition vitreuse (Tg) d'au moins 50 °C. L'invention concerne également un procédé de revêtement d'une canette comprenant un corps de canette et une extrémité de canette, ladite extrémité de canette comportant un trait de coupe. Le procédé consiste à appliquer une composition de revêtement sur au moins une partie d'une surface interne de l'extrémité de canette en recouvrant au moins une partie du trait de coupe, la composition de revêtement comprenant un matériau polyester ; et à durcir la composition de revêtement pour former un film durci, le film durci présentant une température de transition vitreuse (Tg) d'au moins 50 °C, et la canette, lorsqu'elle est remplie d'une boisson gazeuse et scellée, présentant une création de vide par ventilation suffisante lors de la rupture du trait de coupe.
