CrystalFin Crosslinker - 4 fl oz

As an additive to CrystalFin Floor Finish (or, optionally, to CrystalFin), the Crosslinker facilitates hardening.

The 4 ounce Crosslinker bottle contains enough material to make one gallon of finish. Once the Crosslinker has been added, the mixed product must be applied within 48 hours. After 48 hours, the Crosslinker has deactivated, but a second dose can be added to the finish for another 48 hour window of use.
Dalys crosslinker is 73% propylene glycol / 27% aziridine.
