There is a 3,4, and 16 that are easily available retail wise. The lower the number, the thinner it is. 16 is a pretty thick fluid.
Thinner means less working time before it is “set” and technically, less strength if you don’t have it set right.
It melts plexiglass into another piece of plexi- so strength of the bond has a lot to do with how much surface is connected to other surface and coated appropriately with fluid.
3 sets alot faster than 4. When I use 4, I can move parts a bit to straighten or such. With 3 its pretty instant grab and stick…lol
Take a couple pieces of scrap acrylic, glue them together* with your Weld-on 3, let it cure and then try breaking them apart. You should find that the joint is the strongest part, even with the thinner cements.
4 will hold just fine once it sets…it just takes longer which is useful in some instances like gluing two pieces together that need to line up.
For joints I use 3
So the biggest difference between 3 & 4 is how fast they set up?
Pretty much…I cant tell much difference in viscosity but apparently there is a slight difference.
I still have this on my bookmark of “finished looking” acrylic lit signs. I need to find an example of one that would look good “framed” and play with it…couldn’t believe then and even now, what a huge difference this made to the look! #necrogame
