| Doverphos 253 | Dioley Hydrogen Phosphite | A liquid diakyl phosphite with a relatively high molecular weight and low phosphorous content. Mainly use in MWF applications to provide lubricity and anti-wear properties. | 5.3 | 0.910 | 35 cps@25℃ | n.a. |
| Mayphos 45 | Phosphate Ester | Not 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. | 5.5 | 1.070 @60/60℉ | 21500 | Neut.No 200 meqKOH/g Flash Pt. 193℃ |
| Doverphos EP-425 | Phosphate Ester | Light color,low odor,non-chlorinated polymeric phosphite ester suitable for machining/grinding ferrous and non-ferrous alloys.Can be incorporated in neat oils and water-dilutible coolants.Possesses anti-wear and EPproperties;exhibit superior perforrmance in drawing test of carbon steel materials when compared to sulfurizd,chlorinated and phosphorus containing additives. | 4.5 | 0.990 | 500 @ 210F, SUS | acid < 0.5meq KOH/g |
