Abstract
A sealed edge joint can be formed between two metal panels such as an outer vehicle door panel and an inner door panel, by using a flowable sealant bead between the facing surfaces of the two panels, and a thin film of uncured paint-like resin between a flange on the outer panel and the exposed surface of the inner panel. The paint film is cured to a solid impervious condition by a baking operation performed on the completed door panel assembly.
Claims6
A method of forming a sealed edge joint between first and second metal panels, comprising the steps of:
- providing an edge flange on said first panel;
- depositing a bead of flowable sealant on said first panel alongside said flange;
- spraying a film of uncured material onto said flange;
- pressing said second panel against said sealant bead so that the sealant spreads across the joint between the two panels;
- turning the flange onto said second panel so that the uncured material film bonds to the second panel;
- and
- baking the uncured material to form a sealed connection between said flange and said second panel.
A method of forming a sealed edge joint between first and second metal panels, comprising the steps of:
- providing an edge flange on said first panel;
- depositing a bead of flowable sealant on said first panel alongside said flange;
- forming a film of heat-curable bonding material on one of said flange and said second panel;
- pressing said second panel against said sealant bead so that the sealant spreads across the joint between the two panels;
- turning the flange onto the second panel so that the film of heat-curable material is bonded to the second panel and to the flange;
- and baking the heat curable material to form a sealed connection between said flange and said second panel.
