Accu Dyne Full Set 30-60: Precision Dyne Test Marker Pens for Accurate Surface Energy Testing

The Accu Dyne Full Set 30-60 marker pens are specifically designed for testing the surface energy (dyne levels) of films and other substrates. These markers utilize reagent-grade dyne testing fluids and a spring-loaded valve tip that prevents contamination, ensuring the highest level of testing accuracy.

The Accu Dyne Test Marker Pens employ a unique valve tip applicator to separate the fluid storage from the test tip. By pressing the tip firmly onto the substrate, fresh testing fluid is dispensed, effectively cleaning the tip and providing precise dyne level readings. The results are determined by observing how long the test fluid takes to form beads or a continuous film on the sample surface.

Key Features of Accu Dyne Test Marker Pens:

• Available in 16 standard dyne levels, ranging from 30 to 72 dynes/cm.
• Specifically designed for quick, accurate in-line testing by professionals in printing, coating, and laminating industries.
• Ideal for process control or field use by manufacturers of films, sheets, coated boards, inks, coatings, and adhesives.
• The spring-loaded tip meters fluid flow and prevents contamination.
• Suitable for research and development (R&D) and laboratory applications.
• Capable of performing hundreds of tests per marker.
• Compatible with virtually all smooth, non-absorptive substrates.
• Six-month shelf life.
• Customizable combinations of dyne levels and quantities.
• Conveniently packaged in ready-to-use setup boxes.

Important Guidelines for Accurate Results:

1. Avoid contaminating the surface to be tested, as dirt or oils can affect wettability.
2. Always use fresh and uncontaminated Accu Dyne Test™ Marker Pens.
3. Do not retest the same spot; move to a new area of the sample.
4. Store and use the marker pens at room temperature.

Understanding Surface Energy Testing:

Accu Dyne Test™ Pens, also known as Corona Pens, are essential tools for measuring surface energy. These pens quickly indicate the wettability of a surface, which is crucial for ensuring proper adhesion of inks, adhesives, and coatings to polymer-based substrates. Poor adhesion is often due to the low surface energy of these materials, but with surface treatments like Corona or Plasma, wettability and adhesion can be improved.

For optimal adhesion in printing, gluing, or coating applications, it is necessary to increase the substrate’s surface energy. The surface energy can be measured using Surface Energy Test Pens (Dyne Level Testing) based on the ISO 8296 standard.

When the Accu Dyne Test Pen is applied to a surface, the fluid will either form a continuous film or retract into droplets. If the fluid remains as a film for three seconds, the surface energy is at least equal to the dyne level of the test fluid. If the fluid beads within one second, the surface energy is lower than the fluid’s dyne level. Testing with a series of pens with varying dyne levels allows for precise determination of the substrate’s surface energy.
