Recommended Dosage

HiTEC® 4705E additive is based on N,N-disalicylidene propylenediamine and is a 50% dilution in aromatic solvent. The dilution minimises crystallisation of the active material at low ambient temperatures. The recommended treat-rate is 10 ppmv for most applications but this may vary depending on the type of fuel to be treated.
