Make your paint and other finishes last longer with a two-second blast of Bloxygen before you seal the container. The heavier-than-air, pure argon sinks to the surface of the liquid and displaces oxygen, which can cause the finish to cure in the can. As a result you’ll have less skinning, thickening, and spoiling.
The name comes from the fact that it blocks oxygen. Adapted from the food industry, the concept is simple: argon is an inert noble gas. It doesn’t react with anything, it’s non-flammable and non-toxic. There seems to be some confusion by some of the retailers claiming the gas is a mixture of gases including argon, CO2, and Nitrogen, but the manufacturer is quite clear on its website that it’s pure argon.
Each can of Bloxygen is good for about 150 seconds of flow — at two seconds a pop for a quart can of finish that’ll last you 75 uses. Pricing starts at $10 a can.
