VISCOSITY, THE RESISTANCE OF A FLUID TO FLOW, IS REVIEWED IN DETAIL. DISCUSSION INCLUDES VISCOSITY, ITS MEASUREMENT, THE UNITS OF VISCOSITY, ITS TEMPERATURE DEPENDENCE, NEWTONIAN VERSUS NON-NEWTONIAN LIQUIDS, AND THE INFLUENCE OF MOLECULAR WEIGHT ON VISCOSITY. THE IMPACT OF VISCOSITY AND THE PARAMETERS THAT INFLUENCE IT ARE RELATED TO DISPENSING CORRECT QUANTITIES OF AN ADHESIVE TO FORM THE DESIRED BEAD SIZE.
