\n Edge Bonding<\/span>\n and Corner Bonding<\/span>\n <\/h1>[\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]Edge bondings or corner bondings are adhesives designed to contribute to the stability of sensitive and\/or higher components, capacitors or battery cells on printed circuit boards. In addition, these edge or corner bonds ensure the reduction of stresses in sensitive connections, even under high shock and vibration loads and many fatigue cycles. They offer high adhesive strength as well as very good temperature and chemical resistance.[\/vc_column_text]\n

Due to their low curing temperatures, they are also suitable for temperature-sensitive components. After curing, they exhibit low shrinkage behavior.<\/p>\n

[\/vc_column_text][vc_column_text css=””]On request, these adhesives are also available in red or fluorescent coloring to ensure optimum quality and application control: The red coloring or fluorescence makes the quality of the bonding on each individual component easily visible and controllable, even in mass production. The red color in particular stands out visually from the mostly green PCBs.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”1669″ img_size=”full” css=””][vc_empty_space][vc_column_text css=””]Downloads<\/strong><\/p>\n
