A catalyst for curing epoxy resins comprises a tetraalkylphosphonium tetrafluoroborate represented by Formula (1):
1
wherein R
1
, R
2
, R
3
, and R
4
are each C1-C5 linear or branched alkyl and may be the same or different, and the halogen ion content in the tetraalkylphosphonium tetrafluoroborate is 20 ppm or less. An epoxy resin powder coating composition containing this catalyst exhibits a prolonged pot life and can be baked at decreased temperatures.
