Abstract
A structural bonding and sealing system for motor vehicle structural joints may include a first structural joint member including a first bonding and sealing surface, and a second structural joint member including a second bonding and sealing surface. The system further includes the first bonding and sealing surface disposed generally adjacent the second bonding and sealing surface, and the first and second structural joint members generally forming the motor vehicle structural joint. An expandable structural adhesive may be disposed between the first and second structural joint members adjacent the respective first and second bonding and sealing surfaces. The expandable structural adhesive may be expandable to substantially fill an area between the first and second structural joint members, to substantially bond the first and second structural joint members, and to substantially seal the first and second structural joint members from water and air intrusion without use of a separate sealant material.
