Chris C Posted January 8, 2020 Share Posted January 8, 2020 I'm needing to glue a silicone gasket to Acrylic. Can't seem to find any adhesive that will do that. Any suggestions? Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted January 8, 2020 Share Posted January 8, 2020 Depends on what you need. Not much sticks to cured silicone. If you just need to tack it on to the acrylic or a more permanent bond. For a temp deal just use contact adhesive such as spray tack, rubber cement or weatherstrip adhesive. For a more permanent bond use RTV silicon. It sticks real well to clean surfaces such as acrylic i’m an old mechanic.. Link to comment Share on other sites More sharing options...
Chris C Posted January 8, 2020 Author Share Posted January 8, 2020 Yup, the RTV will stick to the Acrylic.............but it won't stick to the silicone rubber sheet I need to make the gasket out of. Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted January 9, 2020 Share Posted January 9, 2020 I think you might be out of luck on that. Honestly I would use relise and form the gasket inpplace with RTV. Link to comment Share on other sites More sharing options...
swedefiddle Posted January 9, 2020 Share Posted January 9, 2020 Good Morning, Loc-Tite 518 will stick. It will fill a void and bond to both sides, It won't set up hard (at least for a long while). Neil Link to comment Share on other sites More sharing options...
Chris C Posted January 9, 2020 Author Share Posted January 9, 2020 On another one of my frequented forums, a friend was facing almost the exact same dilemma a couple of months ago. This is what he purchased and it's worked perfectly for him. I went ahead and ordered some. Pretty pricey, but I'm sure there will be a lot of things I can use it for.

mcostello Posted January 9, 2020 Share Posted January 9, 2020 Silicone conveyor belts are spliced together with something, can't remember the name, but it is a hint to start looking somewhere. It's in a blue tube if it helps. Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 9, 2020 Share Posted January 9, 2020 Around 2+ decades ago when I was a lab guy at Bell Labs, I had an H1 visa guy tell me he needed a connector, I said "provide me the pin out and I'll build it" He said "It's silver coloured" and was adamant that that was all he needed to tell me. So I went around the lab and gathered around 6-8 different silver coloured connectors and gave them to him. None worked. Link to comment Share on other sites More sharing options...

It's in a blue tube if it helps. As I said, mcostello, I've already ordered the glue. I goofed (again) and posted a link to a Youtube video about it and it was removed by a moderator. It's called Tech--Bond Molecular Bonding System. You'll have to do a search if you want to learn about it. I'm not allowed to give you a link to their site. I think it will work great........probably for a lot more things than just this project. Link to comment Share on other sites More sharing options...
