I received a frustrating response from Dow when I asked them for guidance. Because I used the word "marine" in my query, they refused to provide guidance, saying that they do not certify any polycarbonate for marine use. So, not even Dow is willing to answer the question about whether or not a primer is required when bonding aluminum to polycarbonate.
Meanwhile, I know for a fact that polycarbonate is used in architectural scenarios bonder to aluminum frames. Same UV situation as a boat, much higher winds hitting buildings...
Ok, the polycarbonate will fail sooner than lexan. I get it, and it's acceptable to me. Meanwhile, how do I bond it? Frustrating. I guess I'll just clean it as best I can and use the Dow 795 I have, hoping for the best.
