My order of Glacial Acetic Acid arrived! It's typically a water like looking liquid with a STRONG pungent order, but in this shot it's slightly less than 62F°/16C° so it's a solid with long crystals.
I'm going to have a bit of fun at work this next week mixing a custom version of IPS/WELD-ON/SCIGRIP #5 acrylic cement.
WO #5 is a favourite cement of mine, but it's been removed from the market and what supply we do have at work has been claimed by the Production Fabrication dept.
So, some time this next week I need to recreate this ratio.
Methylene Chloride 65%
Acrylic Monomer 25%
Glacial Acetic Acid 10%
Wish me luck!
Oh, and if you hear of the destruction of several major cities in the San Francisco Bay Area . . . I didn't do it.

Do you know which acrylic monomer you will need?
DCM and acetic are easy enough but there are plenty of acrylates to choose from. I guess it depends on the type of plastic you are trying to bond.
Also, I don't much like using dichlor as a solvent. It's used in the glue because it evaporates quickly which is also what makes it a pain to work with. Make sure you've got plenty of exhaust ventilation and/or the proper vapor mask.

Outdoors is definitely a good idea. As is doing this in the shade since the sun will only speed evaporation.
Acrylates are sensitizers so extra care is needed when handling them. You probably already know this.
Doesn't Weld-On make another cement that would work better than trying to formulate your own?

They suggest using #4, which is not as slow as #5 was.
The Acetic Acid dramatically slows the process, allowing the joint to become fully wetted and gives me the time to remove bubbles and for finely dissolved bubbles to dispel.
The result is a wonderfully clear and strong joint without resorting to 2 part acrylic cements.
#1802 might be similar but in talking with the main fab location they didn't find it to be a direct replacement.
