US 2021/0277923 A1 · DEVICE AND METHOD OF APPLYING A SEALANT AROUND A STRUCTURAL ADHESIVE TO PREVENT CORROSION

Abstract

A method of joining first and second vehicle components to make an assembly includes applying structural adhesive and mastic to the first component. The first and second component may be made of different metals, and are brought together and joined at an interface using a linkage. Thereafter, the structural adhesive and mastic are cured. The mastic seals an interior edge of the interface, which is located at an interior of the assembly. A dust sealer is applied and cured to seal the exterior edge of the interface, which is located at an exterior of the assembly. The method results in sealing of all the edges around the entire perimeter of the interface, thus inhibiting water intrusion into the interface and possible corrosion resulting therefrom.

Dependent claims

A multi-material assembly comprising:

a first component including a first metal;
a second component comprising a second metal different from the first metal, the first component being joined at an interface to the second component;
a cured adhesive arranged between the first and second components at the interface;
a cured sealant covering at least one edge of the interface, the at least one edge being arranged in an interior defined by the first component and the second component;
and
a cured sealer covering at least one other edge of the interface, the at least one other edge of the interface being arranged at an exterior defined by the first component and the second component;
wherein the cured sealant, the cured sealer, the first component, and the second component collectively form a closed volume around the cured adhesive.
