Siliconing plastic to glass...

not sure if you read my topic on the 125g with the small chip in it
but long story short
I talked to a custom aquarium builder about the issue and he actually suggested to do that as a "just in case"
also big als (vaughan ontario location) fishkeepers told me they do the same thing...just silicon another piece of plastic over the chip to be safe

Because of how silicone bonds, it will bond dissimiallar materials (ie plastic and glass, plastic and another type plastic) without a problem.
(it's often used between plastics, tile, glass, and porcelin in bathrooms)

I've tried using silicone to seal up acrylic/plexiglass. It doesn't hold up particularly well. You know how with glass you really need a razorblade and actually have to cut the silicone off after its dried....with the acrylic i was able to scrape it clean with my fingernails. Not sure what kind of plastic you're using, but in any case I would probably rough the surface up with sandpaper to maximize the surface area of the bond.
Plastic, acrylic, etc is made with using petroleum products, glass isn't. There is a slight oil content (not that you can see or feel) to them making the use of silicon to be not recommended. This is not to say it won't work, you just won't get the tight adhesion that glass affords nor will you get the longevity.
I'm not sealing anything, so no worries there. The plastic trim broke off the bottom of a 15 gallon (no problems with the actual glass) I recently picked up and so far its holding up okay. Just wanted to know if that would stay like that.
Also thinking of siliconing some plastic containers to the bottom of the tank for this project...the extra weight of the fluorite will help.
