On continuing the heating, the viscosity diminishes while the colour remains the same.
Standard in the ink-jet printing world is to measure the shear viscosity of the liquid.
Now if this state be supposed established in a frictionless fluid, the con sideration of internal friction would simply extend the char acteristics found at any spot to the neighbourhood, and there fore if the boundary were a sphere and so for a frictionless fluid an exception, it would cease to be an exception when we allow for viscosity.
Resin viscosity is the critical parameter in producing fiber composites with low void content.
They act to increase the efficiency of internal mixer mastication of natural rubber and unsaturated synthetic elastomers where reduction of viscosity is required.
