  • Dyne inks are imprecise and subjective

    Dyne inks provide an estimate of surface energy; the Surface Analyst™ produces a rapid, precise, and automated measurement.

     

    Utilization and Road Blocks of Dyne Inks

     

    Manufacturers often employ dyne test inks, used for measuring wetting tension, to estimate surface energy (and therefore, surface cleanliness and treatment level). If you have ever used dyne, you know that applying these inks to your surface requires experience, training, and subjectivity. …Read More

    When Polymer Surfaces are Not Easily Accessible

     

    A recent collaboration between BTG Labs and 3M scientists demonstrates that the Surface Analyst™ can provide receding contact angles. These contact angles precisely match the Wilhelmy-balance values, but in seconds instead of minutes.

    The Surface Analyst does not only apply to small samples of polymer films. It can also apply to manufactured objects of almost any configuration of sample or material.

    This rapid measurement enables the investigation of polymer surface properties not easily probed by other wettability measurement methods such as dyne solutions.
