Result 6:
Material delivered at the beginning of the test strip is hot (low in resin), followed
immediately by material that is cold (low in catalyst), followed by material that is properly
mixed and cures. (See below)
Indicates: system is unbalanced at the beginning of the spray. Low resin is
delivered upon pulling the trigger of the gun followed by low catalyst delivery.
After a moment or two, the system balances and properly mixed material is
delivered.
