Check the label on the original tube.
Likely - but not nailed-on certainty - that it will be the usual BPO (benzoyl peroxide).
But for complete peace of mind I'd suggest getting more of the same that came with your filler.
FWIW as an example Isopon's website says in respect of their own range 'Can be used with all the U-POL and ISOPON polyester fillers. Unique sachet packaging and tube for U-POL dispenser.'

Usual issues are either not adding enough which may cause failure to properly harden - or adding too much which may then bleed through any paint you put over it.
Using too much is the usual reason for running out of hardener while you still have filler left.
