How do we make our own non sticky viscous gel?

TL;DR Summary

How do we make our own non sticky viscous gel

How do we make our own non or very little sticky viscous gel as ever overheard and glimpsed a chat circle of 3-4 persons conferring one another about how making it correctly and had successfully realized one in hand of one of them

But that casual time quite short so one would have no chance to learn or perceive of it well, Iirc it involved base matter e.g. starch or maybe fine wood sawdust mixed with water and maybe glue, then if too sticky it'd be neutralized with some acetone (or s.t. else better)

Anyone really gone through it so that will share experiences now please ?

Is this the slime you can make with PVA and Borax? It can be mixed to be slimy or a firmer version called flubber.

Unfortunately haven't heard that due to my noobs

The point is the gel viscosity is needed to be used reliably enough as suspending/bedding buffer for PCB onto which a component is being soldered

Looks like you came to the right place; I'm quite familiar with various PCBA assembly and soldering processes. Can you say more about your application? What kind of component do you need to hold in place for the soldering process? Is this reflow or wave soldering? Top side or bottom side of the PCBA? The more details you can give us, the better our answers can be.
