Scratch in laminate kitchen worktop

[Acuity31]

Not looking for perfection, just something that will fill it and bond to it well and won't wipe away in general cleaning.
So far just tried Unika Colorfill but I'm not sure if the tube has gone off or what but it never seems to harden up like it's supposed to, and it's sold as something which repairs laminate scratches.

You can buy epoxy resin with a white colour additive in it. That would be fine. I.d dog the scratch out a little when filling to make sure there isn't anything in there to affect bonding.
