This defoamer is made from modified silicon polyether by special technology, it’s a kind of organic silicone product, which is high efficient to remove foams in the etching process of PCB board production.

 Advantages: Excellent defoaming and foam suppressing ability, environmentally friendly, no silicone spots residue to the slot wall, no oil floating or adhesion situation causing during the production, and no any side effect to the following-up processing of the production. 

(1) Strong defoaming and foam suppressing ability, low dosage, no effect to the basic property of foaming system.

(2) Good heat resistance, good chemical stability, non-corrosive, non-toxic, non-flammable, non-explosive, no adverse side effects.

(3) Comparable to the top quality product on market, while the price is much more affordable.

This defoamer apply to:

The water treatment of PCB board. Developing, film-stripping, etching, sewage treatment of PCB board, etc.( The whole PCB production process)  

                                 The application of PCB board cleaning                                                 The application of PCB board production    

Usage:

Direct add this defoamer to the foaming system, or using after diluting with water.

Or adding to the bath solution in advance to suppress the foams forming.

 Recommended dosage：0.1~0.3%, but the optimal dosage should be adjusted based on the actual using effect.
