n.a.
Mayphos 45Phosphate EsterNot soluble in water, but can incorporate in water based formulations when neutralised with alkaline components such as amines. Extremely good performance on non-ferrous metals. Synergism noted with PEG esters or cloud point possessing non-ionic surfactants. Highly recommended in flute grinding applications as the commonly used diatomaceous earth filtration units do not strip the additive from the oil carrier.5.51.070
