    Gluing plexiglass?

    im in a process of making a fitted case from plasti glass for my home media pc, i already have everything cut out but im not sure what glue to use... anybody has experience with this?

    homedepot guy recommended me Locktite that dries clear and said it will dissolve the glass and make a perfect bond. i bought it trusting him without reading the label. came home opened it, and it comes out white like paper glue. read the box: (solvent free-water based glue) wth

    i know for sure epoxy, silicon, or crazy glue wont work as well

    -----------------------------------------------------------
    Best stuff to use for using plaxiglass: Wel-On #4 or 3; and if u have chemist friends best choice is Dichloroethane

    Is this the same as plexiglass? If so, I've used epoxy and it has worked great. You can also use a plastic welder (similar to a soldering iron) although I'm not sure you'll get crystal clear results with it.

    Did you try the locktite, or just judge its performance based on how it came out of the tube?

    yes, don't ask me why i type plastiglass....

    i tried that glue to bond two pieces, it says it dries in 6hrs but 24hrs recommended. it's been over 12hrs since i left it under press and i was able to separate both pieces without any strength. and glue comes off by hand but it did dried clear though

    i didn't have any luck with epoxy either, it does hold better then this Locktite glue.

    i just picked up some other glue, see if that works

    It has to be plastic epoxy. Some types only bond wood and metals.

    JB-Weld is awesome. You might try that. I had good results with epoxy, though. Three years in the car and still holding.

    get "Weld-on 4" - that will melt/fuse the pieces perfectly clear. And get the applicator too for best results.

    I'm building a case too though with PVC and Nylon, not plexi. I recommend you head over to McMaster and search for epoxy and acrylic. I found a couple that might work for you.

    Catalog # -- Description:
    66215A25 -- Devcon 14278 Epoxy Plus
    66215A33 -- Devcon 14315 High Performance

    These are not cheap - they are industrial quality. Head the safety warnings.

    If you think you'll do any more heavy duty gluing in the future, it's worthwhile to buy the applicator gun (74695A71) and a couple packets of mixer nozzles (74695A12).

    plastic epoxy. you'll find it under a lot of names, that loctite stuff likely is just plastic epoxy. don't worry about what color it is when applied, if it says it dries clear then it will

    my fav stuff is at menards, http://www.powerpoxy.com/index2.html

    specifically- http://www.powerpoxy.com/productDeta...?productID=465 it dries clear and takes about 2min to set. its tricky though, you can't move it after that first minute- after it starts to harden after the first minute, it takes a whole 60 sec to fully set. it stays slightly flexible, but holds to plasic like a weld.
