Recommended dosage:

the most effective solution is to add this defoamer into the system before the foams formed.

the dosage concentration shall be determined through the actual defoaming requirement of the system.

Recommended dosage:in a general situation, the starting dosage concentration is 0.3~0.5ml for per liter of bath solution, and then increasing the dosage based on the situation that the bath solution reaches saturation for dissolving the dry film or wet film.
