38 dyne marker pen (4 test markers per set)  is a comprehensive set of 16 pens designed for the quick and precise measurement of surface energy on various substrates. These pens cover a range from 38 dynes/cm and are specifically tailored for on-line use by printers, coaters, and laminators. They also find utility in process control and field applications for suppliers of film, sheet, coated board, inks, coatings, and adhesives.

Key Features:

38 dyne marker pen is Specifically engineered for rapid, accurate on-line assessments.
Ideal for process control or field use.
Suitable for numerous research and development as well as laboratory applications.
Each marker provides hundreds of tests.
Compatible with virtually all smooth, non-absorptive substrates.
Shelf life of six months.

Conveniently packaged in ready-to-use setup boxes.
To ensure meaningful results, it is crucial to adhere to the following four essential guidelines:

Preserve Surface Cleanliness:

Do not touch or contaminate the surface under examination. Dirty surfaces compromise wettability.
Use Reliable Markers:

Avoid using contaminated or expired marker
Prevent Retesting the Same Spot:

Never retest the same location on a sample. Move along the sample or use a fresh one.
Proper Storage and Usage:

Store and utilize unit 38 dynes cm  at room temperature.

Understanding the Purpose:
The Accu Dyne  serves as a complete range of Dyne Pens (also known as Corona Pens) for measuring surface energy. These pens swiftly and effectively determine surface wettability. On polymer-based substrates with low surface energy, achieving proper adhesion of inks, glues, and coatings can be challenging.

Optimizing Adhesion:
To achieve optimal adhesion when printing, gluing, or coating on various substrates, it is essential to increase the substrate’s surface energy slightly above that of the applied material. Surface treatments like Corona or Plasma can enhance wetting, thereby improving adhesion.

Measuring Surface Energy:
The Accu Dyne provides a straightforward method for measuring surface energy. When applied to the surface, the liquid within the pens will either form a continuous film or retract into small droplets. If the Dyne test fluid remains as a film for 3 seconds, the substrate’s surface energy matches that of the ink value in mN/m (dynes). In contrast, if the Dyne test liquid retracts into droplets in less than 1 second, the substrate’s surface energy is lower than that of the liquid itself. You can pinpoint the exact surface energy (Dyne level) by using a range of increasing or decreasing Dyne test pens.

In summary, the accu Dyne  38 dynes unit is an invaluable tool for assessing surface energy, ensuring proper adhesion of various materials, and maintaining product quality in printing, coating, and laminating processes.
