Microwave door gasket? 

Gluing Microwave Door Gasket to Door?

Part of the door gasket on our microwave (it's only 20 years old) came unfastened from the door, then broke off.  A replacement door gasket is no longer made.   Would Gorilla Glue (Stronger Faster) work to re-glue the gasket to the microwave door?

The gasket seems to be some kind of plastic, probably impregnated with metal to shield microwaves.  It looks like it was initially glued in place.  The surface it was glued to appears to be painted metal.

By being used in the microwave, the cured Gorilla Glue would be exposed to steam, temperatures to 212F, and microwaves.

From reading other postings, it looks like I would need to figure out how to clamp it.   Curing time?

Would there be any danger of toxic vapor from using Gorilla Glue in this location, or would everything be reacted?

This will be my first time using Gorilla Glue.  It was suggested by the appliance store.

Re: Microwave door gasket? 

This will be a trial and error application due to your surfaces.  Gorilla Glue will not stick to all plastics.  It works on most, but it will not adhere to polyethylene and polypropylene - high petroleum based plastics we use to make our bottles out of since the surface is too oily and slick and Gorilla Glue cannot stick to it.  Rough up or scratch up the plastic first.  Also scratch up the painted metal as well. 

Apply water to one surface, glue to the other surface, place surfaces together and clamp.  DO NOT close the door as a way of providing clamping pressure!  The two surfaces must be held together tightly for at least 2 hours to be 80% cured; 24 hours to be 100% cured.

Gorilla Glue is 100% waterproof when cured.  If you heat a glue line, the strength will decrease when it's at a higher temperature.  If exposed to temperatures 212 F and higher for a long time (more than 4 hours), the glue line may lose significant strength.  Luckily, microwave use is usually never for a long time!

Good Luck on your repair and I hope it works!
