2 These lubricants: Provide superior resistance to mostchemicals Are compatible with most gaskets,seals and packings Resist washout by water, fuels, oilsand solventsThese greases lubricate over a widetemperature range. MOLYKOTE 3451 Chemical Resistant Bearing Grease hasgood life at temperatures from -40 to450 F (-40 to 232 C);MOLYKOTE 3452 Chemical Resistant Valve Lubricanthas a serviceable temperature rangefrom -20 to 450 F (-29 to 232 C). BothMOLYKOTE 3451 Chemical ResistantBearing Grease and MOLYKOTE 3452 Chemical Resistant Valve Lubricantresist deterioration by solvents, acids,chlorides and other severe chemicalsas well as low-pressure steam andcondensate.

Bearing tests show MOLYKOTE 3451 Chemical Resistant Bearing Grease hasgood life at varying high loads 3451 ChemicalResistant Bearing GreaseMOLYKOTE 3451 Chemical ResistantBearing Grease is an exceptional anti-friction Bearing lubricant especiallydesigned for applications that experiencea wide range of temperatures, loadsand speeds. It is particularly useful inbearings exposed to harsh chemicalsor solvents, bearings used at highspeeds and bearings subjected to heavyloads. MOLYKOTE 3451 Bearing Greasecan be used on: Chemical mixers Needle bearings in circuit breakers Pumps Processing equipment Fuel- and solvent-handlingequipment Sealed-for-life bearings that mustoperate at high speeds, heavy loads,and high and low temperaturesValves protected by MOLYKOTE3452 Chemical Resistant Valve Lubricant show no evidence ofcorrosion or degradation of PROPERTIEST hese values are not intended for use in preparing Molykote 3451 ResistantChemical GreaseValve LubricantNLGI Consistency.
