Hammonds Biobor JF is a liquid diesel and jet fuel additive designed to combat fungus and other microbial life in hydrocarbon fuels, including light oils and transmission fluids. It eliminates slime-producing fungi that clog filters, attack rubber fuel system components, and contribute to metal corrosion. Safe for use with fuel system parts, coatings, sealants, and elastomeric materials, Biobor JF does not negatively affect engine performance. Benefits: Eliminates microbial growth in fuel and water phases Maintains clean fuel systems and pipelines Safe for all tested fuel system materials Increases fuel lubricity, improving engine performance and longevity Exceeds ASTM Standards, MIL-S-53021A, EPA approved, and U.S. Coast Guard certified Applications: Used by aircraft manufacturers, airlines, marines, railroads, fuel suppliers, and storage terminals Prevents filter clogging and system corrosion Treatment Procedures: Drain water bottoms if contamination is severe Apply 270 ppm in fuel for sterilization; maintain at 135 ppm to keep fuel fungus-free Can be batch-blended during tank filling for better dispersion Considered the industry standard for microbial control in diesel and jet fuels.
