Hi, I am new to this great site and here is my first intervention :)
I wonder if anyone has experience with gluing a hopper. I need to ID the material, it is this transparent, acrylic-type kitchen appliance thing Then find a glue for it. Anyone could help me establish what kind of material this is, then recommend a glue for it? I am looking for real experiences and sophisticated adhesives. Of course I can go to a supermarket or hardware store and buy some glues, but I am searching for something industrial. Loctite has some marvelous things and great technical advisory, but at least need to know which material this is. I am in Germany at present, so local products, always convenient, otherwise I source online of course. Thanks all!

UH, welcome. Having the manufacturer of the equipment in question known will go a long way toward identifying what was used. Your question is VERY general, too general to give an accurate reply to.
Are you looking to glue a lot of these or is your one and only bean hopper broken?

Hello and thanks for your answer. Good point! But the material is the typical kitchen appliance thingy. It will be great to have a thread on glues :) The victim is a Eureka Mignon about 10 years old. I am trying to glue my hopper because a new one will set me back USD 40 I bit the bullet and I am trying with a UHU glue for hard plastics. It says that it is developed for kitchen appliances and car tail lights. Let See what happens. If you have any ideas I would like to know. I tend to shy away from off-the-shelf hardware store products, except the Americans. Years ago I called Loctite for a plastic bonding application between acrylic and polypropylene. I was told to use a primer spray and a special superglue. That thing it is holding on for 20 years and counting and everything I glued with that combo held together. I called Hempel/Loctite this morning, the techie there could not bother, then called a local distributor who recommended a 50 Euro glue. Cheers

If it's really acrylic or Lexan, then the standard glue is just a solvent with a bit of dissolved plastic in it. For that application I would use a very thin solvent based version, but it comes thicker if there is a gap.
I don't know what it's called, but they have it around the corner at the plastic fabrication shop. Plastic model cement might work. Try it on the bottom edge and if it melts the plastic it will likely work.
