Viscosity Correction
To accurately predict flow according to viscosity, do the following:
1.
Find the viscosity for the adhesive being used on the “Viscosity”
axis. For this example, use 1200 centipoise.
2.
Project a vertical line upward until it intersects the curve.
3.
Project a horizontal line from this intersection to the “Capacity”
axis.
4.
Read the percent of flow reduction off of the “Capacity” axis
(50%).
5.
In the example used, the flow would be corrected from 2.1
gallons/minute (8.1 liters/minute) to 1.05 gallons/minute (4.05
liters/minute).
