What is eSpray?

eSpray is a revolutionary technology designed to simplify the compressed air spray painting process by controlling three important variables: temperature, gas composition/purity, and static charge. eSpray redefines compressed air spray-painting process by controlling the static charge, producing an electrostatic attraction between the air/material mix and the substrate.

Temperature variations alter paint density and viscosity of the fluid, distorting color, air pressure, and altering the speed of chemical reaction rates in the paint/material, especially solvent evaporation and drying times. eSpray controls temperature, reducing the need for solvents to manipulate viscosity, allowing for predictable, reproducible results.

Gas Purity
Gas purity is essential for a quality finish. Moisture, particulates, and static charge affect the viscosity, spray uniformity, droplet size, and drying speed of spray coatings. eSpray removes oxygen, moisture, and particulates from the compressed air, producing a perfectly dry, anhydrous gas blend, so viscosity is always consistent and oxidation is eliminated.

Static Electricity & Overspray
Friction in the air compression process produces a negative static charge in untreated compressed air. Atomizing paint when forced through a spray nozzle creates additional negative charge. When combined, untreated compressed air and the paint/coatings repel one another. The result is a chaotic, random spray pattern exiting the spray gun as the gas and paint/material particles repel each other. To make matters worse, the substrate also possesses a negative charge after preparation by sanding, polishing, and tacking the surface. The result is static electricity that creates overspray. As much as 40% of the paint/material may end up wasted as overspray that is deposited in the downdraft filters.

eSpray’s patented process removes all oxygen, moisture, and particulates from compressed air then ionizes the residual gas and paint/material mixture, positively charging the combination. The now positively charged mixture is attracted to the negatively charged target substrate. The result is a uniform, consistent spray pattern that is electrostatically attracted to the substrate with virtually no overspray.
