VersaDyne EST
Enables Pad Printing on Olefins
ONE frequently-asked question that we hear from even the most experienced pad printers is: "Why is my ink coming off?" This usually is followed by several other questions from us such as, "What is the substrate?", "Was it pretreated?" and "What is the surface dyne level?" If a customer is attempting to print on any of the olefin group of plastics, the solution will likely include some form of surface pretreatment using the VersaDyne corona treating unit from ITW Trans Tech.
Change Surface Dyne Level
When properly applied to your substrate, corona discharge produces the higher surface dyne levels needed for good adhesion even on the more difficult-to-treat materials like polypropylene and polyethylene. It also enables you to save money by spending less time on your surface pretreating operation because parts can now be treated faster. The VersaDyne unit provides higher power corona treatment at 800 watts of output. That is almost 25% more power than our previous 600-watt version discharge spot treater.
How Does It Work?
VersaDyne changes the surface energy of certain substrates by exposing them to highly charged electrical ions. The two opposing high voltage (12,000 volts) electrodes create this arc of electrons from one to the other. Air is blown between the electrodes, which directs the corona field toward the surface being treated. The electrons change the wettability of the material surface so that the ink cross-links with the polymer surface. Hence, the ink adheres properly to the part. Even the most stubborn ink adhesion headaches can be solved with the high power VersaDyne corona treating system.

Features and Benefits:
- The VersaDyne innovative treating head with ceramic cover is protected for increased durability. Incidental contact will not harm the head or its components.
- The width of the treating field has been increased to 2.5 inches to take care of the majority of pretreating applications. Irregular or three-dimensional surfaces are not a problem for the VersaDyne.

The VersaDyne is available with either one or two treating heads. By running a product under both heads, the application is intensified. This feature can also be used to extend the treatment area to almost five inches by placing both heads side by side with one slightly back from the other.

- The VersaDyne treater does not require any special fixture design or insulation. Common holding fixtures of metal or other materials are not a problem as they would be with many high-output corona treating systems.
- The VersaDyne is a lightweight 66 lbs. and portable to allow easy relocation throughout many areas of your plant.
- This system can be used hand-held or can be mounted above an indexing device to move parts under the corona arc automatically.
- The easily-accessible, adjustable, built-in timer allows the operator to select automatic shutoff of the head after a predetermined time from .3 to 10 seconds.
