Surface treatment solutions from Atmospheric Plasma Solutions (APS) modify plastics, metals, composites and other materials to make them more resistant to corrosion or to improve adhesion of subsequent coatings.
The APD-Series provides an environmentally friendly means of processing materials including surface cleaning, modifying surface energy, and film deposition.
Adhesion, Bonding, and Gluing Enhancement
This atmospheric plasma process can be used to quickly improve the adhesion of two materials. An air plasma treatment of around 100 milliseconds is often all that is needed to greatly enhance adhesion and bonding on difficult-to-bond materials. Even Teflon and silicone surfaces can be plasma treated to provide reliable adhesion using atmospheric plasma technology.
More specifically, atmospheric plasma changes the surface chemistry of materials without affecting their bulk properties. Air plasma creates polar surface groups that impart exceptional wettability on normally hydrophobic materials. This is commonly used to promote adhesion and bonding between dissimilar materials or low surface energy materials such as plastics. Atmospheric plasma treated surfaces have been shown to have enhanced adhesive bond strength, over 15 times stronger than equivalent untreated surfaces. Materials that were previously thought of as being incompatible for bonding can now be successfully bonded using atmospheric plasma technology.
Non-Stick / Anti-Fouling
Non-stick or anti-fouling surfaces are produced by changing the chemistry of the plasma source. Surfaces with Teflon-like stain resistance can be produced by just a momentary exposure to the appropriate plasma chemistry. With specially designed patterning technology, it is possible to make ordered arrays of hydrophilic and hydrophobic regions on virtually any surface. The ability to create these “islands” of different surface chemistries opens exciting opportunities for combinatorial chemistry applications.
APS specializes in systems that electrically produce atmospheric plasma, many of which operate in air without the need for specialty gases. The potential applications of such versatile technology are virtually unlimited, from coating removal and surface treatment to plasma catalyzed chemistry and deposition.
The APD Series of plasma power supplies and applicators is designed for industrial applications requiring between 10 and 500 watts of plasma power. The advanced internal process control software can be configured for automated production use or manual control for process development, through either the front panel or remote control through standard industry remote interfaces. Internal monitoring hardware provides a high level of control of the plasma process, to ensure high-quality, consistent performance.
