Hello,
I am currently working on a gel system that is required to hold metal powder in suspension without separating.
The solvent I have chosen is Xylene with carbopol as a thickener and polyvinyl butyral.
The gel systems seem to be forming well, but once mixed with metal powder, I obtain separation over a 12 hour period.
Any ideas on how to hold the powder in suspension?
I should also note that the gel/powder system cannot be too thick, as it need to be able to flow under 30psi pressure.
Thanks!
