1. The operating time recommended in this table is made based on 1 to 3 seconds per inch (not
minimum or maximum time, this mean variable tolerances) under normal ambient temperature.
NOTE:
When the operating time is set at the actual ambient temperature, it may not correlate
with the set time in the table due to the viscosity characteristics at different temperatures.
