Clear 4oz Can of IPS Weld-On 3 Acrylic Plastic Cement with Weld-On Applicator Bottle and Needle Tip

Matt B: Good Acrylic Cement that contains at least some MEK or a similar chemical. Bonds 3D printed PLA parts to one another easily.

Kindle Customer: I liked that it is methylene chloride based and therefore will really "weld" the Plex. It is best to fit the pieces to be connected carefully together and hold them in place while you put small amounts of the solvent into the joint and allow capillary action spread it through the connection. It is easy to get too much on the work piece and if it runs out beyond the joint it will damage the exposed surface of the Plex. Methylene Chloride (CH2Cl2) is a dangerous chemical if used without proper safeguards. Respiratory protection, eye protection and good ventilation are not too much to ask if you are gluing up a project that will take much more than a few drops. This is NOT a cement you want to give your kids for gluing up model airplanes and such.

Maddentc: Great solution to my "welding" two plastic parts together after breaking.

This is the second can of this product which the first dried up unexpectedly. Noticed on my new can that it leaked if tipped over on the side. The lid seal is not airtight seal, which probably the reason my first can dried up.

Suggest that after opening, you store the can upright. If you can, store in a airtight ziplock bag as the can seal does not appear to be airtight. Hopefully that will minimize evaporation and keeping the toxic fumes in the can.

Suggest the manufacturer find a better way to seal the can, or warn the purchaser of need to carefully/safely store the can.

Devin: I have friends that recommend Weld-On 4 because it runs less, but I like how Weld-On 3 just instantly fills all those tiny gaps. This stuff really does a great job.

There have been some reviews about not being able to open the can. I too had the same problem when it arrived, but then I had a long think about it and realized that the lid may be crimped down. I looked at the can and sure enough, it had a lip just like a paint can. I whipped out my paint-can opener and it did the job. After prying up just a tiny bit as I worked around the lip of the can, I was able to simply twist off the lid.

I read some more reviews that said that the product just evaporated because the can could not be sealed well. What I did was, after getting the cap off, make the tiniest of tiny holes in the lid (which has embossed lettering "cut away to open" or something like that -- I ignored that message and just used a knife to make a tiny hole) big enough to fit the hypodermic end of the bottle into the can.

I just squeezed out some air, shoved the needle in the hole, tilted the can, waited 20 seconds, and I had enough liquid in the bottle to do my glue-up.

Once done, the...
