Product Sheet: DF-550 Defoamer

Date: 3/1/2005

DF-550 additive is a very effective defoamer based on a silica-free silicone emulsion, and is especially designed for water-base systems.  The product is widely used in several fields containing vacuum de-aeration systems and has proved to be superior compared to traditional antifoam types.  The product reduces the surface tension between water and gas, and prevents foam that will normally form in mechanical de-aeration systems.
