The most flexible non silicone on my list is 3M 4000UV (Polyurethane) with an elongation at break of > 700% - much greater than 4200, 5200 or most industrial silicones. I believe this is what Morris uses for deck hardware. It's 3M so if you can get 5200 maybe you can get 4000.
yeah I think 3m is a safe bet...Ill search! and thanks so much!

If you can find a good real commercial supply center, they likely have the right stuff. You want true structural silicone. So if you can find someone who does replacement windows in high rise buildings then they might be able to help. There could be a local product that works well and might even be relabeled version of one of these. 3M products generally are good though, just not 5200.

Re: Proper adhesive/sealer for Lexan

I went to the Dow Corning website, did a search for El Salvador and it returned the regional sales office in Mexico. It might be worth a call to see if there is a retailer for near you where you could get one of the industrial silicones.

For purchasing information, please contact this Dow Corning regional sales office directly.

I used the 3M 4000 on my lexan portlights and it work good with no problems, just make sure to follow instructions and everything has got to be clean... really clean.
