I want to disperse fine metal powder in solvent-free UV-curable mixtures of low viscosity (< 200 mPas). Any particle agglomeration and sedimentazion must be hindered ny the surfactant.
I think you have to use a surfactant with low HLB. I suggest you using sorbitan monostearate or Span 60 (HLB 4.7)
I agree with Mr. Agiba. I've also come across the name "Tween 20% in many papers, but I've never mixed an ink myself.

If you want to get metal particles into an organic solution, maybe you should think of compounds that will specifically coordinate or modify the metal to form a SAM. It probably depends on the metal and whether the surface is metal or metal oxide. Thiols, Carboxlates, Alkyl phosphates can all be used for stabilisation of various metal nanoparticles. Gold nanoparticles can be stabilised with dodecanethiol for example. see Chem Rev 2005, 105,1103-1169
Large particals flee to the top of the 'Müsli' by shaking a mixtur.
(O / V - take a view to masses of the diffrent composites - creating a suitable powder).
Maybe turn the coater onto its head - then any surfcace that has got less mass than your floor.
...This way, an extraordinary shaker containing a pushing convection would be nice ;-)
