What is it indicated for?

BLO 2 X Oxygen Blocker is intended to prevent negative contour in areas where oxygen inhibition of resin polymerization results in premature material loss. Use it before curing composites or Juting to prevent the oxygen inhibition layer from forming. BLO 2 X Oxygen Blocker allows removal of luting resins closer to the final contour before curing, thus eliminating the need to address a large excess of cured composite or luting cement.

Indications for use as stated in the FDA summary.
