MOLYKOTE® 211 Fluid Heat-stabilized dimethyl polysiloxane fluid developed specifically for use in automotive fan clutches Features • Excellent high-temperature stability • Controlled shear viscosity • Provide uniform performance under high shear rates over wide temperature ranges • Minimal viscosity change when subjected to severe heat and shear stresses • No intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS) Composition • Dimethyl polysiloxane • Specialty additive Applications Automotive fan clutches How to use Blending Although the fluid is available in a number of standard viscosity grades, occasionally an application will call for a fluid viscosity between those of the standard grades. Blending different viscosity grades of MOLYKOTE® 211 Fluid permits any desired viscosity. (See Figure 1.) To use the chart: 1. Draw a line between the two points: one on the left-hand scale (representing the high viscosity fluid available) and one on the right (representing the lower viscosity fluid). 2. Draw another line horizontally across the chart at the desired viscosity rating. 3. Draw a third line vertically through the intersection of the first two lines. 4. Read the top and bottom scales for blending proportions to obtain the desired viscosity. Accuracy will be increased by blending the two fluids with viscosities that most closely bracket the desired viscosity. If a very accurate blend is required, the viscosity of the mixture may have to be adjusted using a second blending. EXAMPLE – A 7,000-cs fluid is desired, and 12,500-cs fluid is blended with 4,000-cs fluid. Thus, a line is drawn from 12,500 on
