ONYX AF521

DESCRIPTION

ONYX AF521 is a polydimethylsiloxane, a polymeric organosilicon compund which is ideal to be used as defoaming agent. Very small quantities of the fluid are very effective in controlling foam, especially in lubricating oils. The very high viscosity-index, the thermal and chemical stability, shear-breakdown resistance and the rubber compatibility as well as the compressibility make this fluid outstanding for mechanical and hydraulic uses.
