APS surface treatment solutions modify plastics, metals, composites and other materials to make them more resistant to corrosion or to improve adhesion of subsequent coatings. The APD-Series and DBD-Series products provide an environmentally friendly means of processing materials including surface cleaning, modifying surface energy, and film deposition.
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 is used to change the surface chemistry of materials without affecting their bulk properties. Air plasma creates polar surface groups which 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. Air 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 correct plasma chemistry. With the correct 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.
