I don't know what type of defoamer Kremer 78600 is. Recently I asked
BYK Chemie about their defoamers for preparing dispersions of power
pigments into gum and they recommended me BYK024 with concentrations
between .1 and 1%. I believe this types of products are very similar
and all usually work between .1 and 1% I don't know if this can help.

I bought your book "The Book of Carbon and Carbro" and I consider it
very interesting and helpful.
