The Cortec® Corporation has proudly introduced a major step forward in spray can technology -- EcoAir®-- airpowered spray can products. For the first time, they are providing spray cans powered by compressed air that completely replace expensive chemical propellants. This technology is innovative because a four-layer EcoPouch is inserted into a can then the can pressurized. Finally, the EcoPouch is filled with the liquid. As the valve is depressed the surrounding pressure expels the bag’s internal fluids until the product is used up.
