Description: SYNTHESO D oils are synthetichigh-temperature oils on a poly-glycol basis. They are very resistantto ageing and oxidation and have avery good viscosity-temperaturerelation. Application: SYNTHESO D oils are used for the lubrication of friction points subjectto high temperatures. They are alsoused as pressure fluids in high-temperature applications, and asheat carrier fluids. Owing to thebase oil抯 high pressure absorptioncapacity and good wear protection,SYNTHESO D oils are particularlysuitable for hydraulic or heat trans-fer applications where lubricity hasto be ensured at high temperatures. Application notes: SYNTHESO D oils are suitable for immersion and circulation lubrica-tion systems. If they are used asheat carrier fluids it is important notto exceed a specific load of approx.1.5 W/cm2 in case of free convec-tion and approx. 2 W/cm2 in case of forced convection. The maximum surface temperature of the heatexchanger (film load limit) shouldnot exceed approx. 220 癈. Themaximum permanent service tem-perature of SYNTHESO D oils isapprox. 180 癈. Service temperature range*: SYNTHESO D 32: approx. ?40 to 180 癈 SYNTHESO D 68 und D 100: approx. ?35 to 180 癈 SYNTHESO D 220 bis D 680: approx. ?25 to 180 癈 SYNTHESO D 1000: approx. ?20 to 180 癈 SYNTHESO D 1500: approx. 0 to 180 癈 SYNTHESO D oils are not miscible with mineral oils and syn-thetic hydrocarbons. We recom-mend cleaning the lubrication pointsprior to conversion, and rinsinggears or closed lubrication systemswith the SYNTHESO D oil that will be used for lubrication. SYNTHESO D oils are neutral towards ferrous materials and almost all nonferrous metals. There may be increased wear when thecontact surfaces of design elementsmade of aluminium or aluminium alloys are exposed to dynamic loads(sliding speed and high loads). Ifnecessary, wear tests should becarried out. Depending on the tem-perature and exposure time, syn-thetic lubricants on a polyglycolbase may have an impact on thefunctional capacity of rubber-elasticsealing materials. Seals made ofNBR materials (acrylonitrile-buta-diene-rubber) can be used at per-manent temperatures up to 100 癈.At higher temperatures we recom-mend using FPM (fluoropolymers) or VMQ (silicone rubber) seals. Ithas to be taken into account that different elastomer qualities pro-duced by one manufacturer ordifferent manufacturers may showa different behaviour. Paints may beattacked by synthetic lubricants. When applying SYNTHESO D oilswe recommend the use of two-component paints (reactive paints).Oil gauge glasses should preferablybe made of natural glass or poly-amide materials. We recommend testing the suit-ability of design materials in con-tact with the selected lubricants, especially for series application. Minimum shelf life: The minimum shelf life is approx.36 months if the product is stored inthe original closed container in adry place.
