TEGO® Antifoam represents a range of high-performance defoamers for fossil diesel and also for use in B5/B10 biodiesel. Based on the technology of organo-modified siloxanes, the products are tailored for different fuel qualities and additive combinations. The siloxane backbone ensures low surface tension - one of the basic requirements for a high-performance defoamers. The stability and tolerance is the result of the design of the organic ligands. All TEGO® Antifoam defoamers combine excellent properties with regard to long-term performance, stability in the diesel additive packages (DAPs) and high compatibility in the overall system.
