Plasma surface activation is a process used to improve the wettability and adhesion of materials.
Plasma surface activation is a process used to improve the wettability and adhesion of materials. It is achieved by exposing the material's surface to plasma, an electrically charged gas. This process modifies the surface chemistry and kinetics of the material, for example, increasing the polymer surface tension and making it more hydrophilic (attracted to water). The wettability of the material can then be measured using a contact angle measurement or dyne ink.
Plasma surface activation can be used on various materials, including metals, plastics, and glass. The most common applications are in manufacturing, printing, and packaging, where plasma surface activation-treated materials result in better ink coverage, varnishing, and adhesion. Cold plasma is also commonly used in medical devices and implants as it can improve biocompatibility.
While plasma surface activation is an effective way to improve the properties of materials, it is also a complex process that can be difficult to control. It is crucial to work with an experienced partner to ensure that the plasma surface activation process is carried out correctly.
♦ Dry and Environmentally Friendly: No need for harmful solvents or chemicals.
♦ Non-destructive: Only the surface is modified; the bulk properties remain intact.
♦ Highly Controllable: Process parameters can be finely tuned for precise effects.
♦ Improves Adhesion: Essential for bonding plastics, composites, and metals in advanced manufacturing.
