Plasma FunctionalizationPlasma functionalization is the process by which a bondable surface is treated to improve its adhesive properties, including bondability or paintability.
Oxygen plasma is used in most applications, allowing printing or bonding to a surface that would otherwise be difficult if not impossible to print on or bond to.
The treatment removes organic contaminantes and leaves a free radical on the surface being functionalized, which allows inks and glues to be accepted. These free radicals are chemically unstable and searching for an extra electron, which is why they bond so well.
PrintingPlasma functionalization leaves chemically unstable free radicals on the surface of most materials, allowing printing on a shiny surface that would otherwise smear or resist the ink. These surfaces include plastics and rubber products. The plasma process allows the surface to accept the ink.
BondingThe PE-100 is our most popular system used for plasma functionalization. The convenient chamber size, along with the availability of high frequency RF power, combine to create a production capable unit small enough to fit nearly anywhere in your lab or production work space.
