Hi 7453K,

Great questions! I have a few more myself. dionl, are you looking for surfactants to water-wet a portion of chemistry? If so, which chemicals?

Dionl, could you please provide a little more information so that we can answer your question?

Thanks for your help.

Sincerely,

Eugene

I would go to one of the chemical suppliers of surfactants (like DOW, BASF, CIBA, SURFACHEM..) and let them know what you are formulating - giving them some info about WHAT exactly is in your formulation and what you are trying to achieve by adding surfactant (Better phosphate dispersion? Better wetting? etc..) and the sales rep there should be able to direct you to a suitable range of products.

As I suggested - I still think you would be better off calling the rep from your surfactant supplier and asking them to reccommend a suitable product from their range. That way they can prescribe the best solution for you. Have you had any luck with this?
