During storage, the oxygen or moisture that's sealed in the container continues to cure and thicken your leftovers, ruining them.

Your finish is wasted, this takes time to clean up, and it's messy.
Sometimes, hardened particles can clog spray guns, run the final finish, or destroy the remaining liquid.

Bloxygen (for "blocks oxygen") is a heavy inert gas that prevents oxygen or moisture damage during storage.  Preserve and use every drop; just spray, seal, and store.

In the USA alone, the EPA showed that about 65 to 69 million gallons of paint are thrown away each year, and about 15% of that is oil-based.

That's a line of quart cans from Los Angeles to New York tossed out each year. Each can of Bloxygen can prevent SEVENTY FIVE quarts from oxygen or moisture damage.

Bloxygen uses pure Argon, a powerful and natural inert gas to drive the oxygen and moisture out of your container. Simply blow the oxygen out of your container with Bloxygen and then seal the lid. The heavy and dry inert Bloxygen gas sinks down to block oxygen (or moisture) from the liquid surface of the product that you are storing.

Because Bloxygen is heavier than air, it will separate the liquid surface from any air that may remain in the container.

Bloxygen uses ultra pure argon. We harvest it from our air. This gas is a natural component of our air and the third most common gas on Earth at about 1%.

A full can, because it contains only a gas, feels empty.

The gas is non-toxic, non-flammable, and inert.                                     

Deliberately misusing Bloxygen by concentrating and inhaling it can result in rapid suffocation, asphyxiation, and perhaps death due to lack of oxygen.

There are no CFCs, VOCs, or added propellants. 

It's totally natural. 

Bloxygen can be shipped via the US Postal Service and other carriers because the containers are DOT-reg. 2Q plus (18 bar steel aerosol cans) and they are shippable as a Limited Quantity ID 8000 item (UN# is 1006 /
2.2). 

With an infinite shelf life, each can will provide about 150 seconds of
gas. That's enough gas for 75 uses in quarts. Given that a quart of premium varnish can cost $50 to $100, saving just one half of one quart will pay for your Bloxygen.

The additional 74 uses are "free."

Bloxygen costs less than 20 cents per use.

Everyone has experienced the frustration of hardened paint, finishes that have become rubbery or separated, or oil-based coatings that can never be used again. Bloxygen will save you both time and money by significantly increasing the shelf life of your products and reducing hazardous waste:

• Protects ANY product that is sensitive to oxygen or moisture damage.
• Prevents changes in product chemistry during storage.
• Allows you to store leftovers safely in the original labeled container.
• Reduces hazardous waste and product loss.
• Save time by making finishing projects easier and cleaner.
• Avoid paying a premium for small volumes of finish.
• Improve the quality and consistency of the finish.
• Eliminate spray gun clogs and jams.

For years this problem has frustrated woodworkers and finishers. Of all the attempts to solve this problem (see below) none we've seen are as quick, as safe, or as successful.

• What about marbles? Some folks try to eliminate the air space in their container by throwing marbles or rocks in the liquid. In addition to contaminating their product, they often find that cleaning the marbles results in lots
  of wasted time and product.
  
• What about a smaller container? Transferring your liquid to a smaller container will reduce the air space, but you'll still have oxygen in there. Since the labeling was on the original container, tracking the instruction labels and warnings
  could be a problem.
  
• What about exhaling into the container? As scuba divers or paramedics know, the air we exhale is NOT oxygen free. We inhale 21% oxygen and exhale about 15% oxygen.
  
• What about tipping the container over? Storing your leftovers upside down will only guarantee that the skin will form on the "bottom" of the liquid. Your finish will still be ruined. 
  
• CO2? We use ultra pure Argon because it's totally inert.  CO2 is okay, but it's not totally inert and will react with water to form carbonic acid. 

• What about Air Dusters?  The compressed gas dusters contain difluoroethane CAS #75-37-6 which is flammable when concentrated in a fuel/air concentration of 5.1-17.1% by volume.  Inert gases do not burn.  Given that this is NOT an inert gas, no sound prediction can be made about the effect it will have on the millions of different finishes out there.
  
• What about Propane?  No.  Just NO.  This is dangerous.

Yes.

First, ALWAYS wear Safety Glasses since the finish can splash.

1. Twist the extension tube into the spray tip.
2. Hold lid closely above container and spray towards side of the container to avoid any splash.
3. Spray 2 full seconds for quarts and 4 full seconds for gallons.*
4. Close lid immediately to seal in heavy gas. 

*We recommend 2 seconds for quarts and 4 seconds for gallons
assuming that they are half full. 

Our "rule of thumb" is to spray enough argon gas into the container to fill the head space twice.  So you'll need less gas if the container is nearly full and more if it is nearly empty.

Best Practice? When the container of finish is opened, pour the required amount of finish into a second, user container. Take time (and perhaps use a product like the Paint Plow) to ensure that the original groove is cleaned. Now use the Bloxygen to purge the finish container, seal it, and store it. This will minimize the amount of time that oxygen and moisture can interact with the original product. The finish used in the secondary container should be used up or properly discarded. It will have been exposed to oxygen, moisture, an applicator (rag, brush, etc.) and cannot be returned to your container because of this contamination.

We will make EVERY effort to satisfy any concern.

There are only three problems we've ever seen:

1. Not Enough Gas Used:

The entire storage container must be purged. You cannot use too much gas.

2. Slow Lid Seal / Bad Seal: Once the container is purged, the lid must be immediately sealed into
place.

Make sure that the lid is spotless and dent free to create an airtight seal.

3. Bad Finish: Once oil-based finishes absorb oxygen and skin over or gel, they will continue to have problems during storage.

These finishes will never be the same. Start with NEW finish and use Bloxygen each and every time
it's stored.

The Material Safety Data Sheet is now called the Safety Data Sheet or SDS.
