Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. The most favorable performance is achieved by using the highest-quality base oils. A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. (2;2222;;;;;;;;;;;;;;;;;@@@@@;@@@@@@@@@@@@@@@@@@@@@ " B PAOs are used extensively in automotive fluids as well as hydraulic, gear and bearing oils, working in extremely cold climates or hot applications. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. Furthermore, thermal conductivity at 300F for PAO 6 is 0.085 compared to 0.071 Btuft/(hft2F) for an equiviscous mineral oil, which means that the PAO can conduct 20percent more heat than the mineral oil for better heat dissipation. endobj 1.
