NickE, The alumina that I am using is about 8um in the powder form. We are using this form (pseudo baumite) for its properties, and from our standpoint it is the best chose for our end use. We do not have a lined mill, we have a horizontal and Netzsch mill, I have been using the Netzsch mill...

NickE, I already have alumina in a pretty fine powder, and I don't think I have too much flexibility in changing it. Any suggestions on just working with what I have? Thanks.

I am trying to obtain a submicron particle size for alumina. I am using a mixture of about 60% water, 30% alumina, 5% Petro D-425 and 5% Witconol 14(from Akzo Nobel). I am not fixed on 30% alumina, but I would not want to go below 15%. I have milled my mixture twice and have obtained a mean...

Anyone know of a good resin for a mulch coating, besides ESI-CRYL 1448, 752

I posted a question about flood/float a few days ago about this topic. I am now trying to eliminate the flood/float in the Yellow Iron Oxide, and then I will try the dispersion. I know flood/float in a yellow low viscosity system is common. I have tried several variations of an EFKA...

I have been working on a project to eliminate flood/float. Here is what I am combining... Part 1: DIDP, Surfactant, White Pigment, DIDP Part 2: Part 1, Yellow Iron Oxide, Red Iron Oxide, Special Balck 4 I have tried several surfactants(EFKA, Hydropolat, and Disperplast), coupling agents...
