Testing and Adjusting:
Pour Testing:
The same process and results that are used for testing the spray can be used for testing a pour system.
By pouring a bead of material in an up and down” zig zag” pattern then observing the results.
Note that depending on the length of the mixer there will be a delay in the metering issue
and where it appears on the pattern.
Result 8:
Material delivered at the top and bottom of the stroke is not curing or curing more slowly than the material
delivered in the middle of the up- and down-stroke, see figure above.
Indicates: Low/no catalyst at top (T) and bottom (B) of the pump stroke.
Probable Cause: There is no or improper accumulation effect in the catalyst system. Normally
this is only a problem at high pressures.
Solution: Check to be sure you are using the proper catalyst hose, with or without core. Install a catalyst
accumulator if needed. Check for a restriction in the catalyst system.
