I want to know that nano silver paste of the company if wanting to dissolve which solvent must be used and how?

Hello, using nano silver or Micro Silver in any formulation does not want to dissolve in the formulation. but is the distribution in the formula so it will work Anti-microbial or other action with silver ion. The formula can be in any form. Just ask for it to be thick enough. to prevent powder nano silver or Micro Silver precipitated. Mixing process Ask to blend until the powder is completely dispersed in the formula. Can I use heat or not?
