Focus PAG A125 is a polyalkylene glycol base stock designed as an extreme pressure additive for use in water-reducible synthetic metalworking fluids. PAG A125 exhibits inverse water solubility properties and does not contain chlorine, sulfur or phosphorous.
Focus PAG A125 is completely soluble in water up to 1,000 ppm and is non-foaming. It imparts mild corrosion protection, but additional corrosion inhibitors, such as Focus RP-10, RP-RZ8 or RP-32 are required to formulate finished synthetic metal working fluids. Suggested concentrations in the diluted finished fluid range from 0.1% to .5%, depending on the machining operation.
