Dichloromethane acrylic gluing surface?


#1

I picked up some dichloromethane (weld on 3, I guess?) to glue up some layers of acrylic. It seems to work well, except I layed up on some cardboard and, of course, some drips got underneath everything and stuck to the cardboard. I think I’ll be able to buff or burnish off the cardboard this time but for future reference:

What surface should I be working on that won’t get stuck to my pieces?


#2

Everything will get stuck, because the solvent is softening the acrylic.

The only way to keep it from getting stuck is not letting it touch anything or not using enough solvent to cause drips or runs.


#3

No idea, but wax paper works well for wood glue, parchment paper works well for baking, maybe worth a shot?


#4

Those pointy risers From this post ( I think).
Might still be a problem but only at the points


#5

If you have the piece resting on paper or parchment even if the piece doesn’t still to the material the glue will still wick between the paper and the piece and mar the surface.


#6

I could never precisely control the solvent from a squeeze bottle. I have much better control with a syringe.


#7

yes wax paper will technically work, but the acrylic surface will be blemished. use a syringe or a squeeze bottle with a syringe top:


I do find that the ones I have don’t keep the solvent from evaporation, so between uses i put it back in the metal can

I use a Silicone mat for most of my gluing. Not much sticks to it. I picked it up at Amazon for my electronics hobby but found it works just as well for glue.

Thanks for the input, folks. I’ll give a silicone mat a try along with using a syringe instead of the needle tip bottles.
