The selection of a defoamer for a given formulation must take into consideration many factors, including ink raw materials, method of manufacture, and means of application and cure conditions. The optimum defoamer will be one that balances the strength of the defoamer with the compatibility and solubility of the defoamer in the system. Air Products offers a range of products allowing a systematic approach to defoamer selection based on product performance. In the toughest systems, where foam control is critical without causing defects, Airase® 5400, Airase 5500 and Surfynol® DF66 defoamers, our siloxane-based defoamers specifically designed for aqueous ink systems, offer you the performance you need. These products are specifically designed to have predictable performance in terms of defoaming strength and formulation compatibility. No matter what your formulating needs, Air Products offers innovative and flexible solutions to the challenges you face.
