摘要:
A metalworking oil composition contains: a component (A) that is an ester of a polyhydric alcohol and a fatty acid; and a component (B) that is elemental sulfur, in which the metalworking oil composition has a kinematic viscosity at 40 degrees C in a range from 5 mm 2 /s to 70 mm 2 /s and a flash point of 200 degrees C or more. The metalworking oil composition of the invention is suitably usable particularly in a field of a high-speed cutting work

摘要:
Described herein is an emulsion for use in asphalt rejuvenation applications, comprising an oil phase comprising (1) a polymerized oil comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content less than about 8 wt %; and (2) an aqueous phase, comprising a surfactant. The emulsion may be incorporated into asphalt paving, roofing, and coating applications and especially aged or recycled asphalt thereby obtaining rejuvenated asphalt.
