Bloxygen is a Finish Preserver which lenghtens the shelf life of stains, varnishes, oils and other products sensitive to oxidation and moisiture by preventing thickening and skin-over.
By replacing air in your container with a heavier, inert gas, oxygen and moisture cannot come into contact and affect the product. This will prevent their premature deterioration, which allows you to store them and use them over a longer period of time. Bloxygen is easy to use: Spray, Seal & Store.
Bloxygen can be used for any product sensitive to oxidation and moisture, including oil-based paint, varnish, polyurethanes, catalysts, chemicals, finishing oil, wood fillers, urethanes, stains, gunpowder, marine coatings, some glues, epoxy resin and fuel additives.
Note that lacquer finishes and some latex paints will not benefit from using Bloxygen.
Since Argon is a gas, the full can may feel empty when weighted, but it contains enough gas for approximately 75 uses in quarts.
