    Optic and lens glue

    Has anybody ever used this stuff?

    I found some on Amazon for a couple dollars, and picked up a tube of it.
    Have you guys ever used, or heard anything about this?

    Seems like it would be good for gluing down lens covers and such.
    Such as the build I recently did, shown below.

    Would also come in handy for holding lens covers on Hammond type builds, and basically anything that uses an optic cover without a front bezel.

    Could possibly work for holding down optics.

    I'll have to do some tests once it shows up.

    I'm also curious to test how it affects the light transfer through an optic.

    Looks OK says medium strength .

    only issue I can see is it has solvents in which can have a devastating effect on optics .

    I had an optic craze and self-destruct in front of my eyes when I cleaned it with toulene

    I am using this one at the moment with good results so far

    very clear and easy to use but is a 24 hour cure seems better than the old silly-cone

    I would avoid the use of it around optics. The solvent xylene in this is very similar to toluene that Troutie mentioned eating an optic.

    Go with silicone or for better strength a polyurethane like Sikaflex or 3M 5200 for a flexible bond. I think the adhesive that Troutie linked to is also a polyurethane. Use an epoxy for rigid bonds.

    Thanx for the headsup guys.

    That serious glue looks the biz. May have to give it a shot.

    I have some junk optics and will play around with the stuff I ordered for scientific purposes.....= )
    I will test it out on some scrap polycarbonate as well as some optics that I have laying around. Also have a spare reflector to do some tests on.
    Will post my results.

    I do have some silly cone that is safe for electronic use, but it is hard to work with in small spaces and have it look clean.

    Hoping for a gap filling glue that I can flow into small spaces.

    Need to find a source for the serious glue here in the states.

    For now I will stick to epoxy and silly cone.
