Im trying to glue Lexan on Lexan. What kind of glue should I use? I need something light, because weight is an issue.
I’m not sure if it will work as well with Acrylic/Lexan but this stuff ROCKS with Polystyrene…

I use it to assemble my vinyl models too.
Also this page is a great place to find Arylic/Lexan realted tools materials.
You’ll want to use an adhesive that uses capillary action to bond the material to itself and get the strongest nicest looking seams.
I have had some success gluing Lexan to both Lexan and aluminium with Devcon-30 minute epoxy. www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXC026&P=M
It was cheap and was available at my local hardware store. The only downside was I had to be careful, since it was very easy to get it all over the joint and make it look bad.
General superglue also works, as well any glue that contains cyanoacrylate. However, even if one is careful that stuff can bubble and make rather ugly joints. However, the bonding power is greater than many epoxies, and its perfect for internal parts. I used it for gluing down small posts which I had drilled and tapped for use as mounts.
I use Devcon Plastic Welder No. 14300…McMaster-Carr part 75395 A65. I have never been able to break apart a lexan joint that was epoxied with this stuff.
Rick BrooksThanks for the replies.
Im actually looking for a glue that wouldnt bond the lexan “permanantly”. I want to be able to “snap” them apart if needed. Are the ones you guys mentioned “heavy duty” that it would literally stick them together almost permanantly? Maybe I should go with one the cements from that website: craftics.com/products.cfm?Category=80
Last time, I bought normal crazy/super glue, and it wasnt good at all. It took too long to stick and it ended up as a mess. Also, it “snaps” off too easily, so thats not good either.
Thanks again.
Most of the stuff I recommended actually ‘welds’ the material. The weld is stronger in most cases than the surrounding material.
I’m not sure if there is an adhesive that would bond well and then ‘let go’ without destroying the componants.
Silicone maybe.
I actually used aluminum elbos to make a box (chasis) for my robot and than sealed all the gaps with regular culking. It worked good but after a while you have to replace the culcking becuase it comes off. It is however a good water-tighting solution. (is water-tighting even a word).
Oh ya, sorry for my absense on the sight, homework is murder during mid term.
Dont worry, ill have plenty of my own questions coming up within the weeks to follow.
