    Abstract: This present disclosure relates to a structural adhesive film suitable for bonding a first metal part and a second part, and in particular for hem flange bonding of a first metal part and second part. More specifically, the present disclosure is directed to a structural adhesive film comprising a thermosettable composition which comprises an epoxy compound having a selected average epoxy equivalent weight, a thermoplastic resin having a selected softening point, and an epoxy curing agent. The present disclosure further relates to a thermoset structural adhesive film obtainable by thermosetting of the structural adhesive film of the disclosure, and to a two-part assembly comprising such a thermoset structural adhesive film In another aspect, the present disclosure is directed to a method for bonding a first metal part and a second part, in particular for hem flange bonding of a first metal part and second part.

    Abstract: There is provided a method of making a metal panel assembly, the method comprising: providing a first metal panel having a first body portion and a first flange along a margin of the first body portion adjacent a first end of the first body portion; providing a second metal panel having a second body portion and a second flange along a margin of the second body portion adjacent a second end of the second body portion; providing an elongate adhesive sheet having a first portion near a first end of the width of the elongate adhesive sheet and a second portion near a second end opposite to the first end of the elongate adhesive sheet, the elongate adhesive sheet comprising a thermosettable composition, the elongate adhesive sheet having on at least one major surface a plurality of microstructures; applying the elongate adhesive sheet to said first or second metal panel; folding the first flange of the first panel over said second flange of said second panel; whereby a metal joint is obtained wherein the elongate adhesive sheet is folded such that the first portion of the elongate adhesive sheet is between the second flange of said second panel and said first body portion of said first panel and the second portion of the elongate adhesive sheet is between said first flange of said first panel and said second flange of said second panel; heating the metal joint so as to cause thermosetting of the thermosettable composition of the elongate adhesive sheet, thereby adhering said first and second metal panel and sealing the metal joint.

    Abstract translation: 提供了一种制造金属板组件的方法，该方法包括：提供第一金属板，其具有与第一主体部分的边缘相邻的第一主体部分和第一凸缘;第一主体部分和第一凸缘邻近第一主体部分的第一端; 提供具有第二主体部分的第二金属板和沿所述第二主体部分的边缘邻近所述第二主体部分的第二端的第二凸缘; 提供细长的粘合片，其具有在细长粘合片的宽度的第一端附近的第一部分和与细长粘合片的第一端相对的第二端附近的第二部分，细长粘合片包括可热固组合物， 在至少一个主表面上具有多个微结构的细长粘合片; 将细长粘合片施加到所述第一或第二金属板; 将所述第一面板的所述第一凸缘折叠在所述第二面板的所述第二凸缘上; 由此获得金属接头，其中细长粘合片被折叠使得细长粘合片的第一部分位于所述第二面板的第二凸缘和所述第一面板的第一主体部分之间，并且细长粘合片的第二部分 位于所述第一面板的所述第一凸缘和所述第二面板的所述第二凸缘之间; 加热金属接头，使细长粘合片的热固性组合物热固化，从而粘合所述第一和第二金属板并密封金属接头。
