Result 7:
Material delivered at the beginning of the test spray is cold (low catalyst), followed by
material that is properly mixed and cures. (See above)
Indicates: The system is unbalanced at the beginning of the spray. No catalyst
at the beginning of the spray, followed by normal mix and spray.
Probable Cause: The resin needle is opening too much before the catalyst
needle. This means a shot of pure uncatalyzed resin will be delivered until the
catalyst needle is opened.
Solution: Adjust the catalyst and resin needles to the proper settings.
