Samuel Posted April 2 Share Posted April 2 My friends built in internal filter has de-attched from the glass because it was left in a hot shed, can we use Fourish Super Glue to glue it back onto the glass? Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted April 2 Share Posted April 2 Any cyanoacrylate (super glue GEL) would be aquarium safe and should do the trick. Link to comment Share on other sites More sharing options...
tolstoy21 Posted April 2 Share Posted April 2 (edited) If there is no water in the aquarium, use GE silicon I. It’s bond to glass will be a thousandfold compared to CA glue. Edited April 2 by tolstoy21 1 Link to comment Share on other sites More sharing options...
johnnyxxl Posted April 2 Share Posted April 2 But if the other isn't glass it's not going to bond with the silicone. I would look at epoxy. Link to comment Share on other sites More sharing options...
mynameisnobody Posted April 2 Share Posted April 2 @johnnyxxl how does silicon hold up backgrounds? Only 1 surface it touches is glass, yet it works. Link to comment Share on other sites More sharing options...

Silicon will adhere to many different material but it may be a weak bond. For foam backgrounds, silicone will not adhere to the slick surface of cured "Great stuff" foam. But if you cut off the top layer, it will bond to it. Silicone will form a decent bond to cut edges of PVC material but not to the factory finish surfaces. For my sump filter which use PVC sheet stock, I leave a gap between the PVC and glass then fill it in with silicone. This creates a gasket around the PVC which is a strong bond. 1 Link to comment Share on other sites More sharing options...

I believe super glue does not bond well to glass and silicone may not bond well to the plastic filter. . What you can so, use the super glue/cotton ball trick to create tabs on the filter , this will create a surface for the silicone. So next apply silicone to the glass and super glue tabs.

I find it adheres equally strong to most materials, though I will admit I haven't worked with it that much on plastics. But, glass, wood, ceramics, porcelain etc. it creates a very strong bond (wood being the weakest in that list). I guess one could do a simple test and then adjust from there.
