Adopting special ether with some other auxiliaries as compositions, this defoamer is designed specially for the development process of PCB board production, it has high foam control performance, and it will not cause silicone spots residue to the slot wall, which is more convenient for the equipment cleaning.

In addition that, this defoamer has high chemical stability and water solubility.

 Advantages: No demulsification, mesh clogging, and oil floating in the cleaning liquid, as well no effect to the post-processing. 

(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:

The most effective way is to add this defoamer into the bath solution in turn. Generally, the initial concentration is 0.3~0.5ml for per liter of bath solution, and adding more defoamer based on the required situation when the bath solution reaches saturation as dissolving the dry film or wet film.   

This defoamer also can be used after diluted with water, and for getting the best defoaming effect, it’s better to shake well the product before using.
