Glass to metal cement

[charlie coghill]

I checked Edmond sientific, they have the cement to glue glass to metal, that I need but in too large of quanity. I need maybe a couple of oz.

Some time ago I made the Grandkids some Kaleidoscopes. I used crazy glue but it did not work very long.

Any leads would be appreciated. Thanks.

I've used Liquid Nails Perfect Glue 2 for years with my stained glass projects.

The only one i have gotten to hold up for very long at all was a UV cured glue. Can't remember the specific type, but they should be similar.

All epoxies, contact cements, etc would snap off eventually.

RTV's work very well & are very soft & pliable so that they will allow compliance of the glass with metal of a very differnt coefficient of thermal expansion. Structural epoxies also do well. I have used Armstrong A-12, a rigid material but has good strength, & 3M Scotchweld. The glass should be very clean & the metal cleaned down to "bright " metal

Ultraviolet cured windshield mirror glue is best. Expensive unless you can find it in quantity. Try a local windshield repair shop. If you can convince them you aren't competing with them they might include your required amount in their next order. You will need a UV light source to harden the glue. Sun will work fine but isn't predictable. I was at a trade show last weekend and one of the exhibitors had a handheld UV flashlight for just that purpose for $95.00. Damn near gave myself an eyeball flash burn by turning it on pointed it at my eyeballs.

RTV also works well and is what I use to hold my telescope mirror to the aluminum mirror cell. It requires water to set up which means if the air is very dry it won't set very quickly at all.

I don't recall the brand name now, but I got some gutter calking from Home Depot that sure bonds to metal nicely. I'm certain it would do equally well on glass. It is packaged in a gold and black caulking tube, and cures to a metallic gray color.

Even after years of exposure to sun and weather it remains tough as leather. It literally has to be cut from the metal to remove it (with great effort I might add!).

I think also the polyurethane adhesives, like Gorilla Glue, works on non-porous surfaces like glass.

Silicon based adhesives have worked well for me. Pet shops should sell smaller quantities for repairing aquariums.

That stuff should work just fine.

Not cheap though.

It doesn't take much.

Thanks for the tip on that type of LocTite.
