Bloxygen - Leftover Preserver

Bloxygen preservative allows for safe and convenient long term storing of leftover coating and paint in the original container. Bloxygen is an award winning, natural chemical system that is environmentally safe and easy to use. Simply blow existing oxygen out of the container and seal the lid. The heavy, inert Bloxygen gas sinks down to block oxygen from the liquid surface. Because Bloxygen is heavier than air, it will separate the liquid surface from any air that may remain in the container.

Bloxygen is available direct from Premapro LLC ( in single or multi tin packs. Each tin contains 12 grams of pressurized highly purified argon gas sufficient to preserve approximately 40 – 60 individual 1 quart tins of coating or finishing product. Small quantities and single spray cans of Bloxygen Preservative are available on and can be ordered online.
