Cold Temperature Adhesive

06/30/2009 12:22 PM

I have a refigerator that has hooks on one sides that hold up the bottom draws. On one side both hooks snapped in half. Talked with company and they are clueless for some odd reason. I need to find a glue that can bond to plastic in refrigerator and bond in that coldness

GA, but he'll have to put spreaders to keep it clamped in place. I would also suggest to wait for refer clean out day. Misting it with water will make it set up faster, or even a steam vaporizer, door open of course. Clean the faying surfaces and wait for full setup.

Most liekly would not be able to turn off. I can possibly use a bar clamp to press the hook and hold it to the wall.

Thanks for the help

"both hooks snapped in half"

So, are you bonding the hooks back together or bonding the hooks to the wall, or both?

Hooks back together may be done with solvent, depending on material.

Hooks to wall, I'd go with a polyurethane adhesive.

Both hooks are snapped in half, excessive pressure was applied to the top shelf in which the reaction was snapping in half the hook to both the top and bottom shelf.

If you get frustrated with glue, take short self drilling/tapping sheet metal screws and fasten a bracket. I'm assuming that you have a thick wall. I think moisture may be more of an issue than cold.

You had better be very careful if you are going to drill through the interior wall of the refrigerator, or even screw in some self-tapping screws.

The chiller coils run inside the wall cavity. If you nick one of these thin little coil tubes, you will lose all of your refrigerant in a couple of minutes, and you will be left with a nice white cabinet with a fixed shelf support...

I recall working in the kitchen of a summer camp about 30 years ago, and the assistant cook wanted to put a padlock on a stand-up freezer because the counselors were always sneaking ice cream out of the freezer. So he bought a hasp, grabbed a drill, and proceeded to drill right into a refrigerant coil, causing the freon to spray and sputter out of the hole he made.

These days, I believe that such an incident would be a violation of the Clean Air Act - uncontrolled venting of a regulated refrigerant to the atmosphere...

JMAN is right. ! I was thinking about an old Norge, brand fridge I had taken apart. Drilled holes in two or three places for home made beer. All tubes were in the 'back'. More recently I have seen tubing even in the door in different models/brands. Knew one lady busted line defrosting freezer, and yes freon emptied in mere moments. Ended up replacing. [Don't defrost freezer with butcher knife either.]

Best quick defrost tool is a hairdryer: be careful don't electrocute yourself.

I've placed a pan of tepid water inside also, with quick ' ice off ' action. Not tried hair dryer yet.

You might get away with bonding, if you have that much surface.

Work with me here. You have a hole in the side of the fridge? Right.

You could fashion a new hook from wire, such as a coat hanger. If the hole is big enough, you could use two wires per hole. Use silicone to hold them in place. You might even butter enough on to make it look good enough for the little woman.

Just a thought.

I've made some pretty cool stuff from coat hangers. Also used them as filler metal when building exhaust systems.

Good luck.

I'd have to take issue with your suggestion of epoxy. The clip is molded from a thermoplastic and they don't respond well to epoxy. Especially if the part is stressed.

Hmmm A plastic is a plastic to me (ignorance is bliss). Some of the removable (bottle holder) shelves which fit in my fridge door had the retaining latches broken: I managed to "mold" new ones (using greased insulating tape as the mold) with epoxy. Of course I had the luxury of being able to work "outside" the fridge.

Hey Srock,

Had situation where tabs on clear plastic molded shelf broke on inside of refrigerator door . Used that epoxy that is packaged in cylinder, ( don't remember brand), that one pinches off amount needed and kneads it before applying. This worked great because I could build-up and reinforce the break. The repair has endured a few years, with stress applied in a shear across repaired break.

Hooks have been replaced. Working as good as new. One way of repair that nobody mentioned was to keep calling company until you actually get an intelligent human that can find the correct replacement part. It cost $5 for each hook and took 10 minutes to carefully remove broken pieces and install replacements.

thanks for all the great ideas.
