High temp water proof Cyanoacrylate or better option

[dannyman1982]

Howdy,

I'm looking for the best solution for attaching a hockey puck to a pint glass. Cyanoacrylate seems to be the best option I have found so far, but have had issues with the dish washer. The bond is extremely strong until I'v run it through a dishwasher. I'm not sure if it is the high temp or water that is doing me in. I'm ordering some high temp Cyanoacrylate to see if this fixes the problem, but can't seem to get in touch with a adhesive expert to really set me on the right path. A dishwasher can go up to about 200 degrees F, so ideally something that can easily handle that temp and higher, be waterproof, handle the temp in the freezer, and withstand hockey players as the end consumer. any help would be greatly appreciated!!

I suggest you try a silicone sealant and use a 1/8" bondline thickness. The flexibility of the sealant and the thickness of the bondline will keep the stresses between the adherends low while temperature changes occur. The sealant will only cure about 1/4" deep in 24 hours (it cures by reaction with moisture in the air). Complete cure may take weeks, but that should not matter. Put a glob of adhesive in the center and squeeze the adherends together until the adhesive spreads to the desired diameter, to avoid trapping air bubbles.
