Sikaflex Adhesive
(OP)
Anyone worked with SikaFlex-252, a polyurethane sealant/adhesive, steel to steel? I have a situation where I have to attach a steel plate to an existing steel water tank to avoid welding/bolting and was wondering the durability of the material considering degredation of polyurethane due to ultraviolet radiation.
The material between the water tank and the plate will not see sunlight, but the material on the edge of the plate will. Any problem with a progressive failure of the material from the outside that is exposed to the radiation that anyone has noticed?
I was thinking about holding the material back from the edge of the plate and applying another material to prevent UV degredation, but I may be kidding myself here. Am I overthinking this?

Consider a Dow structural silicone adhesive such as that used in structural glazing applications. Good heat resistance and UV resistance.
If you want to use the urethane, seal the edge with something else like you were thinking.
