Conceptually, if I were interested in bonding a silicone rubber sheet to a carbon steel sheet so that it would "never fail", what adhesives and surface preparations should I be looking at?
The surface is big. Roughly 3 meters x 10 meters. Ideally I'd prefer no seams, but that doesn't seem likely.
Because the surface is big, a cure in place application would not seem possible.
I anticipate the surface to be a bit convex in short direction and generally straight in the long direction.
I anticipate that the surface will not be perfectly smooth. It will be 1 or 2 mm thick sheet spot welded to stringers at maybe 500mm spacing. There will probably be seam welds in the steel sheet.
The entire exterior surface will be exposed to sun and weather. Horizontal. Four seasons. The interior will be climate controlled - except of course when the climate control system is turned off, at which time the interior will be hotter than the outside if it's hot outside, and the same as the outside if it's cold outside.
I cannot tolerate a failure that allows moisture to migrate into the bonding surface.
I cannot tolerate a failure that allows an edge, corner or seam to lift.
I do not trust the installing work force to perform the specified surface preparation correctly.
I do not trust the installing work force to follow the adhesive application procedure correctly.
I'm reasonably sure that given these constraints this is an impossible application. But I'd like to investigate anything might have a chance of working.
